Changes

Gluegen AntTask: 'literalInclude' may contain multiple directories, separated by comma (enhancement)

gluegen stddef/stdint cc header: add missing intptr_t/uintptr_t, proper formating, proper _WIN64 case

remove warnings

windows batch make: bump to 6u26

Newt/AWT: Add singleton test instance lock for all AWT Robot tests, otherwise multiple parallel tests will render the result invalid

NEWT/AWT Unit Tests: Run one test at a time via superclass BeforeClass/AfterClass FileLock

Due to the fact that any test with a UI may interfere
with a UI test (test focus, active, ..), all tests are
derived from the common UITestCase superclass, which
decorates the test class with a FileLock at BeforeClass/AfterClass.

Increased junit timeout to 10 min

Cleanup test/junit structure. com.jogamp.test -> com.jogamp.opengl.text; Compile posted Issue* Bug* snippets

Unit Test Framework SingletonInstance: setup file unlock/delete asap

UI Unit Tests: Add test name to log and singleton lock, better log output

Complete relocation of SingletonInstance.java from JOGL

SingletonInstance Enhancements / Minor Lock/LockExt API Change (isLocked moved up)

We learned that FileChannel.lock() is not reliable on at least GNU/Linux + Sun's JVM implementation,
hence we need a ServerSocket implementation.

Since this code may be useful to others, it has been promoted to GlueGen.

- Abstract SingletonInstance
- Implement Lock interface
- SingletonInstance Spezialisation: FileLock and ServerSocket

Minor API Change: LockExt.isLocked() -> Lock.isLocked()
