Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
fix possible NPE in TruffleCompiler with TraceTruffleCompilation and background compilation enabled. With background compilation, the installed code can already be invalidated when compiledMethod.getCode() is called, in which case it returns null.
