    Hello Everyone,
    
    I would like to request a review for JDK-8146238, recently added by
    Oracle to 8u232 as a BPR.
    
     JBS Issue: https://bugs.openjdk.java.net/browse/JDK-8146238
     Original change: https://hg.openjdk.java.net/jdk/jdk/rev/07556f8cd819
     Webrev: http://cr.openjdk.java.net/~alvdavi/webrevs/8146238/webrev.8u.00/
    
    Besides the usual quirks, patch did not apply clean due to jdk8u not
    having JDK-7188942:
    http://hg.openjdk.java.net/jdk10/jdk10/jdk/rev/d278d6b53fcb
    
    Not having this patch caused some changes in the context, but nothing more.
    
    Additionally, src/windows/native/sun/java2d/opengl/WGLSurfaceData.c
    required moving some variables to the top of the method declaration to
    avoid breaking the build on old versions of Visual Studio.
    
    The patch has passed Tier1 and Tier2 in macosx, linux and windows (x64
    for all of them). No new regressions were found.
    
    Thanks,
    
    David
