From 8ac3f344aded383ca9a3083a877af7bfdf6e1e48 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Wed, 17 Jul 2013 04:27:13 +0200 Subject: Remedy for Bug 782: Issue Debug.initSingleton() or Debug.debug(..) before calling 'PropertyAccess.isPropertyDefined(propName, default)' through Debug class. Calling 'Debug.isPropertyDefined(propName, default)' may be 'optimized' to 'PropertyAccess.isPropertyDefined(propName, default)', which would skip the modules Debug's class initialization. Iff that happens, an AccessControlException may happen, due to requesting an insecure property, since modules own Debug class has not been added it's trusted prefixes from within it's init block yet. This seems to be a bug of the JVM .. to me, however .. the above description is the only able to explain the issue at hand. +++ Fix calls Debug class own static methods, either Debug.initSingleton() or Debug.debug(), before calling 'isPropertyDefined(propName, default)'. +++ Also mark Debug class static methods final! +++ --- src/jogl/classes/jogamp/opengl/egl/EGLDrawableFactory.java | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'src/jogl/classes/jogamp/opengl/egl/EGLDrawableFactory.java') diff --git a/src/jogl/classes/jogamp/opengl/egl/EGLDrawableFactory.java b/src/jogl/classes/jogamp/opengl/egl/EGLDrawableFactory.java index 9c1cc7fc4..5d99e3eba 100644 --- a/src/jogl/classes/jogamp/opengl/egl/EGLDrawableFactory.java +++ b/src/jogl/classes/jogamp/opengl/egl/EGLDrawableFactory.java @@ -84,7 +84,12 @@ import com.jogamp.opengl.GLRendererQuirks; public class EGLDrawableFactory extends GLDrawableFactoryImpl { protected static final boolean DEBUG = GLDrawableFactoryImpl.DEBUG; // allow package access - /* package */ static final boolean QUERY_EGL_ES_NATIVE_TK = Debug.isPropertyDefined("jogl.debug.EGLDrawableFactory.QueryNativeTK", true); + /* package */ static final boolean QUERY_EGL_ES_NATIVE_TK; + + static { + Debug.initSingleton(); + QUERY_EGL_ES_NATIVE_TK = Debug.isPropertyDefined("jogl.debug.EGLDrawableFactory.QueryNativeTK", true); + } private static GLDynamicLookupHelper eglES1DynamicLookupHelper = null; private static GLDynamicLookupHelper eglES2DynamicLookupHelper = null; -- cgit v1.2.3
