EclEmma coverage runs fail when package-info.java is present

[AndreasBrieg]

In Eclipse I tried to run all JUnit tests for the src/test/java directory of a maven project. I get the error message "Error while analyzing package fragment root java at F//target/classes (code 5007).". The system could not find the file package-info.class.

The stacktrace is:

Seems like the ResourceTreeWalker should ignore package-info.

I don't think this is an issue with package-info.class (I have several project with such files).

It is probably refresh issue. If you run Maven in the same workspace than Eclipse will see outdated resources. Please try to refresh your projects (F5) before you run EclEmma.
