I have a GLJPanel with swing components (JInternalPane renders beautifully on top). On render, the parent container/gl event listener (JDesktopPane) calls the game's render, which calls the level's render. Inside the level's render, I have about 24,000 float vertices waiting to be drawn. Cutting the for loop short by a few thousand vertices seems to not crash, but rendering all of them does. Other than that, everything seems to work.
SO.. when I go over, I get spammed with this crap (again, Swing DispatchThread woes -.-):

Here's the code:
This doesn't work:
gl2.glBegin(GL2.GL_TRIANGLES);
for (int i = 0; i < terrainTris.length-6; i+=6) {
gl2.glVertex3f(terrainTris[i].x, terrainTris[i].y, terrainTris[i].z);
gl2.glVertex3f(terrainTris[i+1].x, terrainTris[i+1].y, terrainTris[i+1].z);
gl2.glVertex3f(terrainTris[i+2].x, terrainTris[i+2].y, terrainTris[i+2].z);
gl2.glVertex3f(terrainTris[i+3].x, terrainTris[i+3].y, terrainTris[i+3].z);
gl2.glVertex3f(terrainTris[i+4].x, terrainTris[i+4].y, terrainTris[i+4].z);
gl2.glVertex3f(terrainTris[i+5].x, terrainTris[i+5].y, terrainTris[i+5].z);
}
gl2.glEnd();
This doesn't work:
for (int i = 0; i < terrainTris.length-200; i+=6) {
This, however, DOES work:
for (int i = 0; i < terrainTris.length-2000; i+=6) {
What gives? I tried calling the GLJPanel's paint, repaint and display; in many ways: separate thread, separate thread with sleep, same thread with FPSAnimator, different thread with FPSAnimator, etc, etc.
Am I running out of memory? If so, how can I avoid this? Would VBOs help in any way?
