[rules-users] wierd error : illegal bytecode sequence - method not verified

Hi, I have been using Drools 5.3.0 core successfully in my grails/groovy/java project. The two dependency that are mentioned in my buildconfig file (BuildConfig.groovy) is : //drools runtime 'org.drools:drools-core:5.3.0.Final' runtime 'org.drools:drools-compiler:5.3.0.Final' runtime 'com.sun.xml.bind:jaxb-xjc:2.2.4' Now I wanted to switch to Drools 5.5.0. What I did is I merely changed the version number above. //drools runtime 'org.drools:drools-core:5.5.0.Final' runtime 'org.drools:drools-compiler:5.5.0.Final' runtime 'com.sun.xml.bind:jaxb-xjc:2.2.4' However the tests that were working before are failing now, with some weird error. I am guessing this has to do with conflicting jars or missing jars or whatever and not drools. =============== DEBUG MESSAGE: illegal bytecode sequence - method not verified ================ Jan 17 2013 14:19:57 ERROR business.service.RulesService - Error executing validation drools rules Exception executing consequence for rule "Sale Price Not <= 20 " in business.rules: java.lang.NullPointerException Jan 17 2013 14:19:57 ERROR business.service.AddsService - Error executing validation drools rules Exception executing consequence Any idea what is going on?
