I have been able to reproduce this error repeatedly with pbuilder, but I don't get the test failures outside pbuilder with openjdk-7 and openjdk-8. This issue has already been reported in September (#761523) but was closed afterward.
The cglib package has been replaced by cglib3 and is no longer used in Jessie, so this issue could be safely ignored and/or the package removed from testing. The cglib package is likely to be upgraded to the version 3.x in Jessie+1 and replace cglib3, so it should be preserved in sid.
