Hello AWT team,
Could you please review the reverse changeset:
This undoes the fixes for
- JDK-8039383 "NPE when changing Windows Theme", and
- JDK-8046239 "Build failure in 9-client on all non-Windows platforms"
which cause a regression where JFileChooser hangs in Windows Look-and-Feel.
The proper fix for JDK-8039383 requires some more time.
Thank you in advance,
