NPE thrown by LeftTuple.get() method ------------------------------------ Key: JBRULES-2113 URL: https://issues.jboss.org/browse/JBRULES-2113 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.0.0.CR1 Environment: FOund in 5.0.0.CR1 - Community version. Windows XP Reporter: Tom Murphy Assignee: Mark Proctor the get() method on LeftTuple throws a null exception under certain circumstances, which are as yet undetermined. Here is the Code: public InternalFactHandle get(final int index) { LeftTuple entry = this; while ( entry.index != index ) { entry = entry.parent; } return entry.handle; } Note that the loop moves to each parent in succession, but never checks for entry != null. If it does get to the end of the chain, it will throw an NPE
