While running JOGL in Swing applications on OS X 10.7+ / JRE 7 some issues arise when the JREs 7u10 and 7u12-ea-b08 (2013/01/03, http://jdk7.java.net/download.html) are used.

The next release 7u12 includes a bug fix concerning the positioning of a heavyweight AWT Canvas.

The following test cases render the Gears demo with 4xMSAA into a GLCanvas or NewtCanvasAWT which are added to Swing containers/layouts like JPanel/BorderLayout, JLayeredPane, JSplitPane, and JTabbedPane.

javax.media.opengl.awt.GLCanvas
 - GearsGLCanvas (sole child, BorderLayout.CENTER)
 - GearsBorderLayout
 - GearsJLayeredPane
 - GearsJSplitPane
 - GearsJTabbedPane
   
com.jogamp.newt.awt.NewtCanvasAWT
 - GearsNewtCanvasAWT (sole child, BorderLayout.CENTER)
 - GearsNewtBorderLayout
 - GearsNewtJLayeredPane
 - GearsNewtJSplitPane
 - GearsNewtJTabbedPane

Issues

1. GLCanvas and NewtCanvasAWT are rendered always in the front (7u10 and 7u12-ea-b08).

The canvases are always in front of all layers within the JLayeredPane, althought they should be rendered bottommost.
 
The canvases are always in front of the JTabbedPane no matter which tab is selected.

2. GLCanvas and NewtCanvasAWT are positioned at the lower left corner at start time (only 7u12-ea-b08).

Both canvases are not positioned correctly within their parent container when the JFrame gets visible. Their lower left corner is at the lower left corner of the JFrame. As soon as the canvases are resized they move to the correct position, except for JLayeredPane.

On 7u10 the canvases are always rendered at the right place, except for JLayeredPane.

Questions

1. Does JOGL compensate the positioning bug itself (JDK 7 Bug 2229714 : [macosx] JAWT native CALayer not positioned over Canvas http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=2229714) ?

2. Does this result in wrong positioning in 7u12 or is 7u12 buggy ?

3. How to detect if the wrong rendering is caused by the JRE or by JOGL ?

Wrapping the canvases with a heavyweight Panel has no effect. The colored background area of the canvases are always painted at the right place with the right size. Mouse input is received exactly in this area. All samples run fine on Windows.
