With the update JanosVM is exhibiting the same behaviour.

Xdebugging shows the following:

With the installer code being:

	int cnt = 0;
	while( (checkImage(img,this) & (ALLBITS) ) != ALLBITS ) {
	    try {
		t.sleep(50);
	    } catch (Exception e) {
		System.out.println(e);
	    }
	    if( cnt > 300 )
		return null;
	    
	    cnt ++;
	}

So, it looks like Component.checkImage() was broken between now and march 
of last year (the last time i synced).
