Description

The way the groovyc ant task generates a class name for embedded Groovy from the path of the build.xml file causes errors to be reported when running with IBM's JDK when the path name follows a certain pattern. Here's a specific recipe for reproducing the problem.

Environment:

JAVA_HOME=.../ibm-java-i386-60
ANT_HOME=.../apache-ant-1.7.1
GROOVY_HOME=.../groovy-1.6.3

Put this build.xml in /tmp/a-1.1/build.xml:

<project>
 <taskdef name="groovy" classname="org.codehaus.groovy.ant.Groovy"/>
 <groovy>println 'hello'</groovy>
 <target name="all"/>
</project>

Run

$ANT_HOME/bin/ant -lib $GROOVY_HOME/embeddable/groovy-all-1.6.3.jar

This is the output:

Buildfile: build.xml

Observe the class name "embedded_script_in__tmp_a_1/1_build", which contains a / where the . used to be. IBM's JDK doesn't like this, and I have a feeling it's probably right, though I haven't checked the spec.

I observed this in an environment that was using groovy 1.6.0, ant 1.7.0, and version 1.5.0 of IBM's JDK, but I reproduced it with the latest version of each package.
