Description
The javac compiler's behavior when handling wildcards and "capture" type variables has been improved for conformance to the language specification. This improves type checking behavior in certain unusual circumstances. It is also a source-incompatible change: certain uses of wildcards that have compiled in the past may fail to compile because of a program's reliance on the javac bug.
