Win32 0412 Integration + JDT Core Performance patch for large projects (239b) I hit F4, and after waiting a couple of minutes, the following appears: java.lang.NullPointerException at

The code that causes problem in RegionBasedTypeHierarchy.java is: if (subtypes != null) { for (int i= 0; i < subtypes.length; i++) { this.removeType(subtypes[i]); // line 132 } } This code cannot throw a NullPointerException. This sounds like a jit problem. Which VM do you use? Could you please try with another VM?
Please re-open if you see this problem again with a VM which is not IBM JDK 1.3.1.
