      Just re-build the package with the latest Drools and it should work. (Not tested unfortunately, since we don't have the source file for this particular package.)

      JBoss Rules does not support forward- or backward-compatability of any serialised formats. Versions of packages created in JBoss Rules 4.x are binary-incompatible with versions created in JBoss Rules 5.x For this reason the rebuild button was added to Rules. It is also why the client version must match the JBoss Rules version.

      To work around this problem, you must run with the same versions of the JARs on both the client and the server and, if you add news JARs to the server (regardless of the release) you must rebuild the packages.

      Description

      While trying BusinessRuleProcessor on a package generated with BRMS 5.0, I get an exception (see below). Since this package worked fine with SOA 5.0 (which already has Drools 5.0), I suggest that this is a backwards compatibility issue in between Drools 5.0 and Drools 5.1 that needs to be resolved. The exception follows, the package will be attached in a second.
