To not allow any insecure memory access,
we verify all memory/DMA transfers by tracking the approriate state
of the objects. You have experienced this with your posted exception.
.. com.sun.gluegen.runtime.BufferFactory.rangeCheckBytes
I fetched your attachment, made the little conversion necessary for JOGL2
(sun -> jogamp, and the BufferUtils -> Buffer), plus added the debug and trace pipeline.
See attachement #1.
This shows me the following:
+++
Info: XInitThreads() called for concurrent Thread support
glGenTextures(<int> 0x1, <[I>, <int> 0x0)
glBindTexture(<int> 0xDE1, <int> 0x1)
glTexImage2D(<int> 0xDE1, <int> 0x0, <int> 0x3, <int> 0x100, <int> 0x100, <int> 0x0, <int> 0x1907, <int> 0x1401, <java.nio.Buffer> java.nio.DirectByteBuffer[pos=196608 lim=196608 cap=196608])Exception in thread "Timer-0" javax.media.opengl.GLException: java.lang.IndexOutOfBoundsException: Required 196608 remaining bytes in buffer, only had 0
+++
As you can see, we calculate the proper byte size of 196608, which is to be expected,
but you buffer can't offer any - since it's position is at it's limit.
A simple buffer.rewind() solved your bug, so we can read all required bytes,
see attachment #2.
Now the output is:
+++

glGenTextures(<int> 0x1, <[I>, <int> 0x0)
glBindTexture(<int> 0xDE1, <int> 0x1)

...

And the cube is no more yellow :)
