Bug 1363: Java 11: JAWTUtil: Use sun.awt.SunToolkit.awtLock/Unlock and disableBackgroundErase (impl. semantics)
Commit 13c6bbbde5ea476d60e0a2f04a5172d3302d0edd simply removed the
AWT commonly used SunToolkit lock/unlock methods, which was incorrect.
It lead to certain resources access collisions as access has to be synchronized
using the same reentry lock across AWT and NativeWindow/JOGL.
We utilize the new com.jogamp.common.util.UnsafeUtil of GlueGen commit 07c1885e9a3d1f3a3853414648c06fb3864bc69f
to disable the IllegalAccessLogger while fetching the methods/fields and making them accessible.
JAWUtil also hosts access to SunToolkit's disableBackgroundAccess(Component)
aligning the code for GLCanvas, NewtCanvasAWT and AWTCanvas.
