I have the exact same issue when adding a pkg file created by guvnor into kbuilder. So Knowledge Agent has nothing to do here.
KAgent is failing in the following lines:
is = resource.getInputStream();
Object object = DroolsStreamUtils.streamIn(is);
I do not have an access to the source code right now, but does "DialectRuntimeRegistry" have a "private static final long serialVersionUID" defined? The error you are experiencing usually happens when the Java class compiled by the client is different (have a different serialVersionUID) from the same Java class compiled by the server. You have two options: 1. To define "private static final long serialVersionUID" with a constant number in that Java class, this way the client and the server compiled class will be identical 2. Compile both, the client and the server Java class on the server, and copy the .class to the client ( dirty option ) /Anatoly org.drools.rule.DialectRuntimeRegistry doesn't define serialVersionUID. The error seems to be fixed after declare serialVersionUID field. I'm running a full build to make sure this fix doesn't break any test. |
