It looks like glGet(GL_MAX_ELEMENTS_VERTICES) is what you
need. However, this glGet seems to only be associated with
glDrawRangeElements, not glDrawArrays.

OpenGL for Java does almost no additional work beyond calling
down to OpenGL; however, it is definitely possible to crash the
JVM in the same way it is possible to crash a C program using
OpenGL.
