ChangeLog for Avalon Excalibur 4.0
<ul>
<li>Update user docs. [BL]</li>
<li>Remove dead code in scratchpad. [PD]</li>
<li>Rework thread pooling package to a new design. This
 provides a mechanism to run a cleanup thread when
 the JVM is killed. [PD]</li>
<li>Add classloader extension framework into the extension
 package. [PD]</li>
<li>Add Container mechanism from Avalon Phoenix. [PD]</li>
<li>Add support for recursive property resolution.
 Added appropriate unit test to accompany feature.
 (Property utils). [PD]</li>
<li>Problem Fixed: I've encountered a problem with the
 SingleThreadedPool in that it alternatley returns
 valid and null pooled objects until you've got the
 "initial" constructor argument + 1 and then it starts
 returning (Poolable)m_factory.newInstance().
 Submitted by: "Corey O'Donovan". [PD]</li>
<li>Fix some bugs found by Pool Profiling tests. [BL]</li>
<li>Add new resource monitoring facility. This allows
 you to actively monitor resources and be notified
 if they are changed by outside forces. [BL]</li>
<li>Set hierarchy via constructor to allow LogKit to
 work in sub classloaders. Submitted By: Sylvain
 Wallez. [DP]</li>
<li>Update FileUtils with methods to count size of a directory,
 input argument check, fix javadoc, and method to
 convert an array of Files into URLs. [DP]</li>
<li>ClassLoaderObjectInputStream moves from Cornerstone
 to Excalibur. [PH]</li>
<li>Promote the i18n ResourceManager code to Excalibur
 production. [DP]</li>
<li>Updated log messages for JdbcConnection--as well
 as added runtime detection if no connections could
 be created. This provides better reporting if the
 connection has configuration errors or other mitigating
 errors. [BL]</li>
<li>Add direct support for Informix connection pooling.
 Requires the most recent JDBC drivers from Informix
 to use this feature. [BL]</li>
<li>Deprecated the oradb attribute in JdbcDataSourceComponent,
 and added a keepalive element.This way we can test
 the line with valid SQL statements no matter what
 the DB is. Informix had trouble with the "select 1"
 and I am sure there are others. [BL]</li>
<li>Fix bugs found by ReadWriteLock Test Case in the concurrent
 package. [BL]</li>
<li>Update component package with support for Paremeterizable
 components (patch from Mircea Toma) [DP]</li>
<li>Add support to display if an option is required. Patch
 was from Tom Jordahl (from xml-axis project). [BL]</li>
<li>Fixed bug "CLArgsParser loops infinitely on OPTIONAL
 options" like "-Fa -B" where F optionally has an argument.
 Added unit tests to verify that it has been fixed. [PD]</li>
<li>Update javadocs with '@since' tags so that we know
 when components have been introduced. [JT]</li>
<li>Update JDBC datasource component so that you can
 specify your keep-alive query. This is for databases
 that don't like "SELECT 1;" as a query. [BL]</li>
<li>Add new JUnit TestCase for automatically setting
 up Avalon Components and running tests. [GP]</li>
<li>Fix a number of tests, and provided a couple new tests. [BL]</li>
<li>Fix build process for tests and fix some of the tests. [PD]</li>
<li>Add new LogKit Management framework to allow each
 component to have unique logger implementations
 and provide fine grained control over logging. [GP]</li>
<li>Add new JNDI package to Excalibur with Memmory and
 RMI providers. [PD]</li>
<li>Updated Announcement.xml to not refer to Testlet
 anymore. [BL]</li>
</ul>
