[rules-users] OutOfMemoryError: GC overhead limit exceeded - RESEND

[Jeffrey Schneller]

This is a RESEND because of mail server issues.  Not sure if the
original message went out.

 

I saw a similar thread about this back in March but I am now seeing a
similar exception being thrown.  I am running 5.0.1.  The error is
thrown in my app after the change set listener determines there was a
change with the rules package in the Guvnor.   I have included the stack
trace from the most recent time the exception was thrown.  Hopefully
someone can provide some additional information or a workaround.  Has
this problem been fixed in 5.1?  If so, has 5.1 moved out of M2 state
and into a CR state and when will it go into a full released state?
