+ Commons BeanUtils Package
+ Version 1.9.1
+ Release Notes
+
+INTRODUCTION:
+============
+
+This document contains the release notes for this version of the Commons
+BeanUtils package, and highlights changes since the previous version.
+
+For more information on Commons BeanUtils, see
+o http://commons.apache.org/beanutils/
+
+Release 1.9.1 is a bug fix release which addresses a problem with the new
+feature of custom introspection introduced with release 1.9.0. It is fully
+binary compatible with the previous release. The minimum required Java version
+is 1.5.
+
+BUGFIXES in version 1.9.1
+=========================
+* [BEANUTILS-456]
+ For PropertyDescriptors obtained via custom introspection now additional
+ information is stored to prevent that write methods are lost during
+ garbage collection.
+
+ Release Notes for version 1.9.0
+
+Release 1.9.0 contains some bug fixes and improvements that have accumulated
+after the 1.8.3 release. The most obvious change is that the new version now
+requires JDK 1.5 or higher, and that language features introduced with Java 5
+(mainly generics) are used. A new feature has been introduced, too: the support
+for customizing bean introspection.
+
+Compatibility with 1.8.3
+========================
+Adding generics to the BeanUtils API has been done in a backwards compatible
+way. This means that after type erasure the resulting classes look the same as
+in the previous version. A drawback of this approach is that sometimes it is
+not possible to use the logically correct type parameters because then
+backwards compatibility would be broken. One example is the BeanMap class: The
+class is now a Map<Object, Object> while its keys actually are strings.
+However, implementing Map<String, Object> would change the signatures of some
+methods in an incompatible way. More details about limitations of the
+generification can be found at
+https://issues.apache.org/jira/browse/BEANUTILS-452
+
+One exception from the compatibility rule is the ResultSetIterator class which
+now implements the Iterator<DynaBean> interface. This causes a change in the
+return value of its next() method. ResultSetIterator is used internally as the
+iterator implementation within ResultSetDynaClass (it is probably a mistake that
+it is public). So chances are minimal that this change affects existing code.
+
+Another change which may affect compatibility is [BEANUTILS-379] (details can
+be found at https://issues.apache.org/jira/browse/BEANUTILS-379). Older
+versions of BeanUtils contained some classes that were copied from Commons
+Collections. These classes have now been removed, and a dependency to Commons
+Collections has been added; the collections jar now has to be contained in the
+classpath, too.
+
+Except for the change on ResultSetIterator and the additional dependency to
+Commons Collections, Commons BeanUtils 1.9.0 is fully binary compatible with
+the previous version 1.8.3.
+
+Changes on Converters
+=====================
+The convert() method in the Converter interface now uses a type parameter in
+the following way:
+
+ <T> T convert(Class<T> type, Object value);
+
+This makes it possible to access the converter's result in a type-safe way.
+Applying generics in this way revealed some inconsistencies in the Converter
+implementations. There were situations in which converters could return a
+result object of a different type as was requested. This was not a problem
+before because the result type was just Object. Now the compiler complains if
+a converter's result is not compatible with the desired target type.
+
+Because of that Converter implementations have been made more strict. A
+converter now checks the passed in target type, and if it cannot handle it,
+throws a ConversionException. This prevents unexpected results and makes
+converters more reliable (it could be considered a bug that a converter returns
+a result object of a different data type as the passed in target type). In a
+typical scenario, when converters are accessed via ConvertUtils, this change
+should not cause any problems because the converters are only called for the
+data types they have been registered for. But if converters are used directly,
+they might now throw ConversionExceptions when they did not in a previous
+version.
+
+BUGFIXES in version 1.9.0
+=========================
+* [BEANUTILS-454]
+ BeanUtilsBean.copyProperties() no longer throws a ConversionException for
+ null properties of certain data types. This fixes a regression introduced in
+ version 1.8.0. The issue is related to [BEANUTILS-387].
+* [BEANUTILS-411]
+ BeanUtilsBean.setProperty throws IllegalArgumentException if getter of nested
+ property returns null.
+* [BEANUTILS-408]
+ MethodUtils.invokeMethod() throws NullPointerException when args==null.
+* [BEANUTILS-426]
+ ConstructorUtils.invokeConstructor(Class klass, Object arg) throws
+ NullPointerException when arg==null.
+* [BEANUTILS-380]
+ BeanMap methods should initialize the root cause of exceptions that are
+ thrown when running on JDK 1.4+.
+* [BEANUTILS-379]
+ Remove copied Collection classes.
+* [BEANUTILS-378]
+ BeanMap does not work in osgi (fixed by BEANUTILS-378).
+* [BEANUTILS-381]
+ MethodUtils getMatchingAccessibleMethod() does not correctly handle
+ inheritance and method overloading.
+
+New features in version 1.9.0
+=============================
+* [BEANUTILS-425]
+ Support customization of introspection mechanism.
+* [BEANUTILS-428]
+ Provide a BeanIntrospector implementation which supports properties in a
+ fluent API.
+* [BEANUTILS-455]
+ WrapDynaBeans can now be configured to use a specific instance of
+ PropertyUtilsBean for introspection or property access.
+
+Other changes in version 1.9.0
+==============================
+* [BEANUTILS-452]
+ Add generics.
+* [BEANUTILS-449]
+ LocaleConverters do not take the target type into account.
+* [BEANUTILS-448]
+ LocaleConverters do not check their default value.
+* [BEANUTILS-447]
+ LazyDynaList.toArray() is not conform to the contract defined by the
+ Collection interface.
+* [BEANUTILS-446]
+ Some of the converters ignore the passed in target type.
+* [BEANUTILS-445]
+ Converters can return an invalid result object if a default value is set.
+* [BEANUTILS-441]
+ Replace UnmodifiableSet.decorate with Collections.unModifiableSet.
+* [BEANUTILS-436]
+ Replace package.html with package-info.java.
+* [BEANUTILS-438]
+ Add @Deprecated and @Override Annotations.
+* [BEANUTILS-437]
+ Replace Date and Revision SVN keywords with Id.
+* [BEANUTILS-431]
+ Remove @author tags and move missing authors to pom.xml.
+* [BEANUTILS-432]
+ Switch to Java 1.5.
+* [BEANUTILS-429]
+ Delete trailing white spaces and white spaces on empty lines from all files.
+* [BEANUTILS-427]
+ Configure Checkstyle to check for trailing white spaces and white spaces on
+ empty lines.
+
+
+ Release Notes for version 1.8.3
+
+Compatibility with 1.8.2
+========================
+BeanUtils 1.8.3 is binary compatible release with Beanutils 1.8.2, containing only bug fixes.
+
+BeanUtils 1.8.3 requires a minimum of JDK 1.3.
+
+Memory Leak
+===========
+A memory leak was found in BeanUtils 1.7.0 (see BEANUTILS-291) which was fixed
+in BeanUtils 1.8.0 for JDK 1.5+.
+
+Testing of BeanUtils 1.8.1 revealed that the leak still appears to exist
+in IBM's JDK 1.6 implementation.
+
+
+see http://issues.apache.org/jira/browse/BEANUTILS-291
+ http://issues.apache.org/jira/browse/BEANUTILS-366
+
+
+BUGS FIXED:
+===========
+
+The following is a list of the bugs fixed in this release, with their Jira issue number:
+
+ * [BEANUTILS-373] - MethodUtils is not thread safe because WeakFastHashMap which uses WeakHashMap is not thread-safe
+ * [BEANUTILS-371] - Add constructors which have useColumnLabel parameter to ResultSetDynaClass and RowSetDynaClass
