Hi,
Should we submit a new bug or complete the opened bug with this reproducer ?
It is quite critical for OpenJDK 11 adoption as I expect linux
distributions at least will provide icedtea-web for javaws support, even
for 11+.
I will try implementing a workaround redirecting EDT using a single
AppContext... to reduce the opportunity to have deadlock = only 1 EDT used
at the same time.
Regards,
Laurent
