REGRESSION : Last worked in version 15.0.2

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
jpackage with developer signing. I'm assuming any time at java 16 but haven't tried to do any additional isolation.
My command includes...
--mac-package-identifier "org.mik3hall.halfpipe" \
--mac-sign \
--mac-signing-key-user-name "Michael Hall"


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
built and signed application
ACTUAL -
The build stops with an Exception thrown on codesign

---------- BEGIN SOURCE ----------
Signing information as above
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
For now I eliminated signing

FREQUENCY : always
