when showing any refactor dialog when running with jdk 1.8.0_152-b16 or
later

I have added some screen shots showing any outstanding locks on the stack. It looks like it is syncing on "this" and not the tree lock.
In Component:
{code:java}
public synchronized void addContainerListener(ContainerListener l) {
{code}
In ParametersPanel (that calls show)
{code:java}
public synchronized RefactoringSession showDialog() {
{code}

> Sometimes (or almost always), when you try to do some refactor action, NetBeans freezes. It appears that a lock is obtained on a panel when the dialog is shown, and the AppKit Thread tries to get the lock while trying to add an accessible listener to it.
