Unique Residual Errors in jogl-utils

I only have one place which I'm not quite sure whether my revision is correct or not. Can anybody help to double-check it?

src/net.java.joglutils.msg.test/DisplayShelfRenderer.java
around line 160, is it correct to revise

sharedPbuffer = GLDrawableFactory.getFactory(GLProfile.getDefault()).createGLPbuffer(new GLCapabilities(GLProfile.getDefault()), null, 1, 1, null);

to

sharedPbuffer = GLDrawableFactory.getFactory(GLProfile.getDefault()).createGLPbuffer(null,new GLCapabilities(GLProfile.getDefault()), null, 1, 1, null);

cheers
