Bug#1108572: junit5-system-exit: FTBFS with default Java 25

[Vladimir Petko]

Dear Maintainers,

Would it be possible to consider the MR[1] as a proposed solution for
this issue.
The 1.x version of the library used Security Manager and 2.x was
rewritten to use instrumentation.
The users of the library will have to replace -Dsecurity.manager=allow
with -javaagent:/usr/share/java/junit5-system-exit.jar.
I have prepared the version upgrade MR and pushed upstream and
pristine-tar branches.

Best regards,
Vladimir.
