This is using the latest JDT core (tag v368). I have a file with missing types. Every so often when I hit save I hit an NPE in FieldDeclaration.resolve which dumps one of the following stack traces: java.lang.NullPointerException at

Could you please provide a testcase ?
Cannot do anything until steps to reproduce are provided. Please reopen then.
Timed out
As of now 'LATER' and 'REMIND' resolutions are no longer supported. Please reopen this bug if it is still valid for you.
