Array Index Out of Bounds in ClassFieldInspector with certain method signatures ------------------------------------------------------------------------------- Key: JBRULES-2217 URL: https://issues.jboss.org/browse/JBRULES-2217 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.0.1.FINAL Environment: JBOSS 4.0.5, Windows Server 2003 Reporter: Justin Waugh Assignee: Mario Fusco Fix For: 5.4.0.Final, 5.3.1.Final If a class has a method named setXXX but is not a traditional bean method, (particularly that it does not have a single parameter and returns a value) an ArrayOutOfBoundsException will be thrown during class processing from ClassFieldInspector.storeGetterSetter (line 261). This is because in ClassFieldInspector.processClassWithoutByteCode() it improperly detects the method as being a getter, because it does not filter by method name prefix when trying to process get/is methods, but uses the common method ClassFieldInspector.addToMapping() to handle the method. an example problem method name would be: public boolean setDefaultValueAndCheckValidity(); Granted, methods like that might not be ideal programming style, but shouldn't break the processor
