Any clues?

It's a known issue of Eclipse 3.7 running on Java 7.

Possible workarounds:

  • use JRE7u5 (last version)
  • when using JRE7, theres a small rarely documented feature set system property java.util.Arrays.useLegacyMergeSort=true This should use old implementation and should not bring up the bug (I haven't tested, but you can search for the property ;-) )

See bug 317785 for detail.
