The following files and libraries in the extension module cause conflicts on the
Java classpath:
/lib/alfresco-test.jar
Ambiguous resources on the Java classpath render the behaviour of the JVM
undefined (see Java specification).
Although it might be possible that the repository can still start-up, you can
expect erroneous behavior in certain situations. Problems of this kind are
typically very hard to detect and trace back to their root cause.
It is possible that these conflicts only exist in specific ACS versions. Run this
tool with the -verbose option to get a complete list of versions where each of
these files has conflicts.
