#108 emma fails to instrument with an IndexArrayOutOfBounds

[Leon Rosenberg]

I have multiple projects which include the same build file (parts) but all fail in the instrumentation task. The same projects run perfectly with emma-eclipse-plugin. Whenever I'm starting them from ant and console I get:
emma-compile:
[instr] processing instrumentation path ...

the task definition is derived from the example in the user-guide:
<project name="emma">

<!-- directory that contains emma.jar and emma_ant.jar: -->
<path id="emma.lib" >
<pathelement location="${lib.build}/emma.jar" />
<pathelement location="${lib.build}/emma_ant.jar" />
</path>

<taskdef resource="emma_ant.properties" classpathref="emma.lib" />

<!-- output directory used for EMMA work files and coverage reports: -->
<property name="coverage.dir" value="${output.dir}/coverage" />
<property name="instr.classes.dir" value="${output.dir}/classes-instrumented" />

<target name="emma-prepare">
<mkdir dir="${instr.classes.dir}" />
</target>

<target name="emma-compile" depends="emma-prepare, test-compile" description="turns on EMMA instrumentation/reporting" >
<property name="emma.enabled" value="true" />
<!-- EMMA instr class output directory: -->
<emma enabled="${emma.enabled}" >
<instr instrpathref="test.classpath"
destdir="${instr.classes.dir}"
metadatafile="${coverage.dir}/metadata.emma"
merge="true"
/>
</emma>
</target>
</project>

I've tried it with both available versions:
emma-stable-2.1.5320-lib.zip
emma-2.0.5312-lib-zip

MacOSX 10.6, Java 1.6.0_07-b06-153, 64 bit.

Can this bug be related to 2119913?
