> Please review this patch adding new lint option, **lossy-conversions**, to > javac to warn about type casts in compound assignments with possible lossy > conversions. > > The new lint warning is shown if the type of the right-hand operand of a > compound assignment is not assignment compatible with the type of the > variable. > > The implementation of the warning is based on similar check performed to emit > "possible lossy conversion" compilation error for simple assignments. > > Proposed patch also include complex matrix-style test with positive and > negative test cases of lossy conversions in compound assignments. > > Proposed patch also disables this new lint option in all affected JDK modules > and libraries to allow smooth JDK build. Individual cases to address possibly > lossy conversions warnings in JDK are already addressed in a separate > umbrella issue and its sub-tasks. > > Thanks for your review, > Adam
