Hello, Please review the fix for jdk9. Bug evaluation was done by Anton: http://mail.openjdk.java.net/pipermail/awt-dev/2016-April/011177.html
This is a cross-platform bug it affects d3d/ogl pipelines. The problem is that BufferedContex cached information to skip some native reconfigurations. But this cache cause a memory leak if some data(src/dst surfaces) was cached and there was no new rendering in this context(we create context per-d3d_device/ogl_config).
In the fix I changed all these caches to weak references. Note that i use a references as initial values instead of null, just to eliminate the null checks in the body of the method.
The test was updated to be more stable(flushed the EDT + flushed the Disposer thread).
