        Description

        FULL PRODUCT VERSION :
        9.0.1

        ADDITIONAL OS VERSION INFORMATION :
        Win10 x64

        EXTRA RELEVANT SYSTEM CONFIGURATION :
        Java 9.0.1

        A DESCRIPTION OF THE PROBLEM :
        The right ALT key has extra bits set when calling KeyEvent.getModifiers() which causes ALT + ? hotkeys to fail.
        Even Swing dialogs like JOptionPane.showMessageDialog() don't work (ALT+N ALT+Y don't work).
        Only the right ALT is affected.

        REGRESSION. Last worked in version 8u152

        ADDITIONAL REGRESSION INFORMATION:
        1.8_152

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Upgrade to 9 or 9.0.1 and right ALT no longer works as expected.

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        Right ALT works.
        ACTUAL -
        Right ALT returns ALT_MASK and ALT_GRAPH_MASK bits.

        REPRODUCIBILITY :
        This bug can be reproduced always.

        ---------- BEGIN SOURCE ----------

        ---------- END SOURCE ----------

        CUSTOMER SUBMITTED WORKAROUND :
        Downgrade to 8.0
