[jdk11u-dev] RFR: 8317920: JDWP-agent sends broken exception event with onthrow option [v2]

[Johannes Bechberger]

> Fixes the bug that is in the JDWP-agent since JDK 1.5.
> 
> The original patch did not apply cleanly because Virtual Threads and instanceof patterns are not present in JDK 11 and the Debuggee class changed slightly.
> 
> Tested on Mac M1 with the added test case, the code is platform-independent.
