Hi, Andy.
I suggest to check the latest jdk9 and jdk8. Do you able to reproduce this bug on jdk8u112?

The best solution I've found so far is to use reflection to dig in and
null out the 'target' fields on the LWComponentPeer and CPlatformWindow
after disposing.  This at least allows the JDialog/JFrame instance to be
GC'd (along with any heavier objects they may reference), but isn't
optimal since ultimately the LWComponentPeer and CPlatformWindow
instances still end up leaking.  Another problem with this approach is
that we have hundreds of uses of JFrames/JDialogs across our codebase
and this workaround would require each one of them to be modified to add
this special cleanup logic; I'd like to avoid that if at all possible~

Any suggestions?
