Bug 1181 - JOGL WebStart Applications using GLCanvas/AWT may Deadlock by two AWT-EDT on Java >= 1.8.0_45
Root cause:
- AWT Toolkit global Lock
Our locking scheme (AWT-EDT-1):
- Surface Lock
- sun.awt.SunToolkit.awtLock()
- Component.getGraphicsConfiguration() -> synchronized(Component.getTreeLock())
Other AWT-EDT-2 by Webstart:
- synchronized(Component.getTreeLock())
- sun.awt.SunToolkit.awtLock()
Results in a deadlock.
Solution:
- Issue Component.getGraphicsConfiguration() before awtLock(),
where Component.getGraphicsConfiguration() is being used to
detect possible reconfiguration.
- Also use updated AWTGraphicsConfiguration's GraphicsConfiguration
if no 'new' detection is required.
