The attached FileDialog-based reproducer crashes the JVM with:

# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00007f71c81cd0cc, pid=87550, tid=87576

To reproduce:

Expected:
A file dialog is shown and no crash happens.

Actual:
JVM crashes. Example hs_err is attached.


It is assumed that this has to do with the build environment and runtime environments of the JDK. For example using the latest upstream OpenJDK 11.0.12+7 build from [1], crashes on F34. Using the same version from the system package, java-11-openjdk, doesn't crash. Builds from [1] are built on a RHEL 6 build machine. Also, when running on an older system, like RHEL 7 or RHEL 6, the reproducer works fine (using the same build).
