(In reply to comment #0) > Build Identifier: In Helios download ?jdt 3.6.0 > > /** > <p>This code sample demonstrates what appears to be a bug in the Helios > compiler. Reproduced on HEAD. Thanks for the report, I'll follow up. Problem related to null references and flow analysis. We don't set the constant pool name since the code containing the anonymous type is found to be unreachable by one phase. But then another phase ignores the reachability and attempts to retrieve the constant pool name and operates on it ending up with NPE. Thus the left hand is unaware of what the right hand is doing. Ayush, please follow up. This is a regression in 3.6, so needs to be fixed for 3.6.1 Created attachment 176386 [details]
