[webkit] [9] Review request for 8153151: Call JavaScriptCore GC whenever JVM GC happens

[Arunprasad Rajkumar]

Hi Kevin, Alexander, Guru,

Please review the below patch.

JIRA: https://bugs.openjdk.java.net/browse/JDK-8153151

Webrev: http://cr.openjdk.java.net/~arajkumar/8153151/webrev.00

Issue: Few JVM heap objects(ImageDecoder, Font,..) are held by JavaScript garbages.

Fix: Add a dummy object to com.sun.webkit.Disposer, DisposerRecord.dispose(..) will be called once JVM GC's our dummy object. Call JSC's GC function from DisposerRecord.dispose(..).


Regards,
Arun
