[jboss-jira] [JBoss JIRA] (DROOLS-858) NoSuchMethodError on JIT Compilation of non-primitive comparison

NoSuchMethodError on JIT Compilation of non-primitive comparison ---------------------------------------------------------------- Key: DROOLS-858 URL: https://issues.jboss.org/browse/DROOLS-858 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 6.3.0.Beta2 Reporter: Sascha Dirbach Assignee: Mario Fusco Fix For: 6.3.0.CR1 Attachments: ConditionEvaluator898a83b4ea6745eaa1b63420a059d717.class A LHS like this: {code} $map : Map() $simpleTestObject : NonStringConstructorClass (something=="simpleTestObject") Entry ( getKey() == $simpleTestObject ) from $map.entrySet() {code} fails at runtime with a NoSuchMethodError, when incompatible objects are compared (Map with object vs. custom Object) and the execution is jitted. The generated evaluation method looks like this: {code} public boolean evaluate(InternalFactHandle paramInternalFactHandle, InternalWorkingMemory paramInternalWorkingMemory, LeftTuple paramLeftTuple) { LeftTuple localLeftTuple = paramLeftTuple; NonStringConstructorClass localNonStringConstructorClass2 = (NonStringConstructorClass)this.declarations[0].getValue(paramInternalWorkingMemory, localLeftTuple.getHandle().getObject()); Object localObject = ((Map.Entry)paramInternalFactHandle.getObject()).getKey(); NonStringConstructorClass localNonStringConstructorClass1 = localNonStringConstructorClass2; if (localObject != null) { if ((localObject instanceof NonStringConstructorClass)) { localObject = (NonStringConstructorClass)localObject; } else { localObject = new NonStringConstructorClass(localObject.toString()); } } else { tmpTernaryOp = (localNonStringConstructorClass1 != null ? 0 : true; break label123; } label123: return localNonStringConstructorClass1 == null ? false : ((NonStringConstructorClass)localObject).equals(localNonStringConstructorClass1); } } {code} It seem that, a fallback for primitive types was included, by calling the constructor of an object with the object's toString() output: {code} localObject = new NonStringConstructorClass(localObject.toString()); {code} At runtime this fails, if no such constructor exists.
