LinkageError with IBM JDK >= 8.0.5.6

This is a tracker issue for IBM JDK issue (to be reported).

After upgrading to recent IBM JDK (8.0.5.7), we have encountered LinkageError exceptions (see below) when building a KieBase in Arquillian tests and GWTMockito tests. The problem does not happen with IBM JDK 8.0.5.5, we have managed to create a reproducer not involving Drools nor EAP, a bug is going to be reported for IBM JDK.

The GWTMockito one:
