I'm seeing a problem using ant that I suspect is related to the classloading.
I think it came in build 107 or 108.
The following
<path id="modules.antcontrib.classpath">
<pathelement location="${build.install}/ant-contrib-1.0b3.jar" />
</path>
<taskdef resource="net/sf/antcontrib/antlib.xml"
classpathref="modules.antcontrib.classpath" />
Is failing with
/mydir/build.xml:27: taskdef class "ignore"/> cannot be found
using the classloader AntClassLoader[/mydir_build/ant-contrib-1.0b3.jar]
This would seem like a pretty common use case.
If I comment that out, then I get the following. The named class is in the
specified jar file.
/mydir/build.xml:578: typedef class name="p4versionstring"
classname="weblogic.ant.taskdefs.perforce.P4VersionString"/> cannot be found
using the classloader
AntClassLoader[/mydir2/weblogic.ant.taskdefs.perforce_1.1.0.0.jar]
