Luc Dew commented on FELIX-3568:
--------------------------------
Hi, it is really quite a blocker for Java7 adoption for us.
Using the XX:-UseSplitVerifier JVM option fixes the issue but we have to set it
for Maven surefire plugin (so that Junit test pass) and in the startup
parameters of our OSGi based servers.
Also since the UseSplitVerifier use a fallback mechanism testing first with the
Java7 verifier and rolling back to Java6 verifier, it has an impact on class
loading time.
