The following might be interesting for developers of 2D games/LWJGL developers:
Agil2D is a reimplementation of (a large subset of) Java2D based on OpenGL (namely GL4J). With a few exceptions, the performance seems to be much better. Especially text drawing got much slower, unfortunately. The implementation even supports Swing.
Here’s the URL: http://www.cs.umd.edu/hcil/agile2d/index.shtml (the HCIL is already well known for Jazz, a zooming UI framework or PhotoMesa, one of the coolest applications I’ve ever seen, using Jazz)
So whats about a LWJGL port of Agil2D? 
At least in theory…
