Build ID: Build id: M20080221-1800 Steps To Reproduce: Significant use of generics and inner classes may be causing the problem. The chance of duplicating the error with a test case seems prohibitive to even think about.

LookupEnvironment.createParameterizedType(line 725) is passed null as the genericType from line 1121 in LookupEnvironment : ReferenceBinding memberType = parameterizedType.genericType().getMemberType(memberName); // NO check to see if this is null ... parameterizedType = createParameterizedType(memberType, typeArguments, parameterizedType);
Seems to be a case where: ReferenceBinding memberType = parameterizedType.genericType().getMemberType(memberName); returns null. If you have a case that is causing the problem in a reproducable way, you can provide it to us even if the test case is big.
Definitely a scenario which we need to reproduce to assess a good fix.
Julia - do you know if this problem has happened again or just the one time ?
Julia - this appears to be the same problem as bug 244762 Somehow we cannot find a member type referenced from a .class file. Do you know if you're using libraries compiled by other compilers?
Julia - please reopen if your problem is not fixed with a recent 3.5 stream build Closing as a duplicate of bug 244762 Stack trace is the same as https://bugs.eclipse.org/bugs/show_bug.cgi?id=244762#c3 *** This bug has been marked as a duplicate of bug 244762 ***
Verified for 3.5M3.
