From 9291731fec7103301ba36511ceb4375f63170e5c Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Sun, 11 Dec 2011 04:47:27 +0100 Subject: Fix concurrency bug of GLProfile initialization ; Fix SharedResourceRunner 'dead' thread (Applets) GLDrawableFactory: - clarify: public getWasSharedContextCreated(..) -> protected createSharedResource(..) - add: getSharesResourceThread() GLProfile: - proper locking of initSingletion(..) path: - Use RecursiveThreadGroupLock and add/remove GLDrawableFactory's sharesResourceThread while creating it's the sharedResource. This simplifies and fixes GLProfile's locking code. - Fix and simplify initSingleton(boolean) API doc - mark it deprecated. - Add initSingleton() for controlled initialization only, pairing w/ shutdown(..) Remove initSingleton(boolean) calls in code and test! +++ Fix SharedResourceRunner 'dead' thread (Applets) In Applets, stopping an Applet makes the browser Java plugin interrupting and killing all related threads, including our SharedResourceRunner thread. - Validate whether the shared resource thread is alive - Catch interruption in shared resource thread and assume it's a kill signal - releaseSharedResource: clear devicesTried set --- src/jogl/classes/javax/media/opengl/awt/GLCanvas.java | 1 - 1 file changed, 1 deletion(-) (limited to 'src/jogl/classes/javax/media/opengl/awt/GLCanvas.java') diff --git a/src/jogl/classes/javax/media/opengl/awt/GLCanvas.java b/src/jogl/classes/javax/media/opengl/awt/GLCanvas.java index 329bb125e..ab4276dee 100644 --- a/src/jogl/classes/javax/media/opengl/awt/GLCanvas.java +++ b/src/jogl/classes/javax/media/opengl/awt/GLCanvas.java @@ -1047,7 +1047,6 @@ public class GLCanvas extends Canvas implements AWTGLAutoDrawable, WindowClosing // System.err.println(NativeWindowVersion.getInstance()); System.err.println(JoglVersion.getInstance()); - GLProfile.initSingleton(false); GLDrawableFactory factory = GLDrawableFactory.getDesktopFactory(); List availCaps = factory.getAvailableCapabilities(null); for(int i=0; i
