[rules-users] Jetty NoSuchMethodError Lorg/eclipse/jdt/core/compiler/CategorizedProblem

I am running some drools application code through Jetty and I get the following error. I'm guessing its something to do with a conflicting jar or dependency? Any help would be much appreciated. It does not happen when I run it through tomcat 7. java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/CategorizedProblem; at org.drools.compiler.commons.jci.compilers.EclipseJavaCompiler$3.acceptResult(EclipseJavaCompiler.java:375) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:335) at org.drools.compiler.commons.jci.compilers.EclipseJavaCompiler.compile(EclipseJavaCompiler.java:405) at org.drools.compiler.commons.jci.compilers.AbstractJavaCompiler.compile(AbstractJavaCompiler.java:49) at org.drools.compiler.rule.builder.dialect.java.JavaDialect.compileAll(JavaDialect.java:405) at org.drools.compiler.compiler.DialectCompiletimeRegistry.compileAll(DialectCompiletimeRegistry.java:46) at org.drools.compiler.compiler.PackageRegistry.compileAll(PackageRegistry.java:107) at org.drools.compiler.compiler.PackageBuilder.compileAll(PackageBuilder.java:1218) at org.drools.compiler.compiler.PackageBuilder.compileAllRules(PackageBuilder.java:955) at org.drools.compiler.compiler.PackageBuilder.addPackage(PackageBuilder.java:943) at org.drools.compiler.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:507) at org.drools.compiler.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:714) at org.drools.compiler.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:51) at org.drools.compiler.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:40) -- View this message in context: http://drools.46999.n3.nabble.com/Jetty-NoSuchMethodError-Lorg-eclipse-jd...
