Some test data contained precompiled java classes that were removed during packaging process.
These zip archives were affected:

 ./org.eclipse.mylyn.context/org.eclipse.mylyn.context.tests/testdata/projects/project1.zip
 ./org.eclipse.mylyn.context/org.eclipse.mylyn.context.tests/testdata/projects/project2.zip

Contents of these archives are stored uncompressed in directories project1 and project2
respectively. If you want to run the tests in org.eclipse.mylyn.context.tests, each project
should be recompiled and compressed with zip to restore the original archive. Directory
structure of *.class files should be located in bin/ folder inside the archive and the
directory containing bin/ and src/ should be the root of the zip directory tree.
