Description Wade Walker 2011-08-21 16:54:03 CEST 
The recent change to EGLDynamicLibraryBundleInfo so that shallLookupGlobal()returns true causes an exception when launching an applet from within Firefox 6 and Chrome 13 on Windows. The EGLDrawableFactory static initializer fails due to lookupSymbolGlobal not being supported on Windows, so we get this stack trace from the Java console:

If you change WindowsDynamicLinkerImpl.lookupSymbolGlobal() to the following, it fixes the problem:

    public long lookupSymbolGlobal(String symbolName) {
        if(DEBUG) {
            System.err.println("WindowsDynamicLinkerImpl.lookupSymbolGlobal: Not supported on Windows" );
        }
        return 0;
    }

More details: Java 1.6.0_23, Windows 7 64-bit, NVIDIA GeForce 8800 GTX, driver 8.17.12.7533 (5/2011).

Sorry, forgot to mark as confirmed. I tested the fix on FF, Chrome, Safari, and IE 9 on Windows, and they all work.

Also: isn't WindowsDynamicLinkerImpl.java supposed to be auto-generated? I looked for the .cfg file that contained the code to throw the exception, but couldn't find it. It looks like this formerly auto-generated file is now checked in?
