Possible Bug in Janino

Starting with 3.0.7 (I suspect with this commit ), Janino appears unable to find some classes on the classpath.

This repro explores two almost identical cases:

• a simple script that imports junit.framework.TestCase.
• the exact same script, plus a class named junit.framework.nested.Breaker added to the classpath

The first script succeeds, while the second fails -- see example output.

Running the Repro

run ./run-repro from a bash shell.

Notes

• Package names matter -- when I have encountered the problem, there is a class whose package name shares a prefix with the class to be imported.
• Classpath order matters -- if you move target/classes to the end of the classpath both runs succeed.
