Build Identifier: 2.0.1.v201108020636 The attached Xtend class (using the Xtend tutorial project) does not compile to java due to a NPE thrown in the Xtend/Xbase compiler. The call hierarchy to reproduce the error is as follows: - recursiveMethod (Return type declared) - method1 (Return type declared) - method2 (No return type declared) - recursiveMethod (Return type declared) The circumstances are very specific and in any of the following cases, no NPE is thrown: - In case of a declared return type for method2 - In case of a direct call to method2 from the recursiveMethod - In case of no call to recusriveMethod in method2 See the attached files for more details and the stack trace. Reproducible: Always Steps to Reproduce: 1. Import the Xtend tutorial project 2. Copy the attached Xtend class in to the xtend.tutorial.basics package 3. Check the Eclipse .log-file for an NPE
