I have spent a day just to debug a silly error.
So I post here and hope that it helps other people:
I have a NullPointerException when application starts with stack trace:
As you can see: there is no way to debug this error because it happens inside the JVM.
After a lot of testing I found that:
I have a manager A which contains a manager B and I override B::isFocusable() and returns true.
So, avoid this if you can.
