Here's a testcase which proves Mr. Sekiguchi's point.
------------------------------------
<project name="test-whichresource" default="dotest">
<target name="dotest">
<whichresource property="testresult" class="org.apache.tools.ant.Main"/>
<echo message="${testresult}"/>
</target>
</project>
-------------------------------------
In Ant 1.7 alpha the output is:
dotest:
[echo] ${testresult}
With the diff suggested the output is:
dotest:
[echo] jar:file:/usr/local/ant/lib/ant.jar!/org/apache/tools/ant/Main
.class
Here again is the diff:
Index: src/main/org/apache/tools/ant/taskdefs/WhichResource.java
