[jira] Created: (XMLBEANS-151) XMLBean Ant task fails with NullPointerException when run from within Maven
XMLBean Ant task fails with NullPointerException when run from within Maven
---------------------------------------------------------------------------
Key: XMLBEANS-151
URL: http://issues.apache.org/jira/browse/XMLBEANS-151
Project: XMLBeans
Type: Bug
Components: Compiler
Versions: Version 2 Beta 1
Environment: Windows XP, JDK 1.4.2_06, but I suspect this is not relevant
Reporter: Ian Springer
When I execute the XMLBean Ant task from within a Maven goal, it always fails with the following stack trace:

at org.apache.xmlbeans.impl.schema.SchemaTypeSystemImpl.<clinit>(SchemaTypeSystemImpl.java:150)
... 37 more
I attached to the JVM and found that the following line is causing the NPE:
("org." + "apache." + "xmlbeans").equals(SchemaTypeSystem.class.getPackage().getName()) ?
Specifically, SchemaTypeSystem.class.getPackage() is returning null. The JavaDocs for java.lang.Class#getPackage() say that it "[returns] null if no package information is available from the archive or codebase." I think it's returning null in this case because of how the classloaders are set up by Maven. To verify that it has something to do with running inside Maven, I ran the Ant task with the same exact arguments from within vanilla Ant, and it worked fine.
Note, I tried setting the fork attribute on the task to both "true" and "false", but I get the NPE either way.
Note, the XMLBean Ant task with the same parameters works fine when using XMLBeans v1.0.4.

---------------------------------------
Thanks, that's great news! Sorry for the duplicate issue; I only scanned open issues for existing issues, but should have searched all issues for "SchemaTypeSystemImpl" or "getPackage".
