Re: [ajdt-dev] Eclipse 3.1M5 and status of AJDT 1.2.0M3

[Barry Kaplan <groups1@xxxxxxxxxxx>]

Should the compiler be able to handle classes that use generics? (I couldn't find anything on the website that identifies the capabilties of the current compiler for this build, so maybe I cannot yet use aspectj for my java5 projects?)

I'm getting a NPE from the compiler for the class below. If I exclude this class from the build, another single file fails with the same error.
