To reproduce, run the following on a Mac aarch64 system (e.g., M1):

$ export JDK_HOME=/path/to/jdk-22-or-later/Contents/Home
$ gradle -PFULL_TEST=true sdk :systemTests:test --tests PangoTest

This will crash as follows:

#
# A fatal error has been detected by the Java Runtime Environment:
#

The hs_err log is attached.


For an easier way to reproduce this, run the attached test program (which was derived from PangoTest) on macOS using JDK 22 or later on Mac (either Intel or ARM) with any recent JavaFX build.

$ java CoreTextCrash

It will bring up a window and crash right away.
