font-family:"Courier New"'>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?<o:p></o:p></span></p>
