Error for mutation analysis of Common-Collections

[neelofarhassan]

Hello,

Compiling Common-collections using "defects4j compile" works fine, however, "defects4j mutation" gives this error.

@neelofarhassan

Thank you for the report. I am able to reproduce the issue. We will look into it and see what we can do to fix it!

I was also able to reproduce this. Seems like a backward-compatibility issue (Java 7 vs. Java 8). We are about to update Major in Defects4J; I'll test the newer Major version on Collections to see whether this solves the problem.
