While adding additional debug statements to the native code, I noticed that in the block that throws
the Java exception there is no rtc->DetachThread() before exiting!
Having copied that block from another part of the native function (from a location before an
rtc->AttachThread()) and adjusted the lines that were specific to checking the scope argument I have
not checked for a missing rtc->DetachThread()!
Adding rtc->DetachThread() makes the raised RexxCallContext condition available and the signal
handler takes effect.

The conditionObj NativeActivation::checkConditions() is NULL right before
returning.
That would suggest you are using the wrong context to raise the exception, because the one you
used was returning true for CheckCondition(). CheckCondition() just checks the value of the
conditionObj variable.
Added debug output in native code. "root_RII" is the (primodal) Rexx instance that is globally
available. Also the context gets shown its threadContext and threadContext's instance.
Here the relevant ouput:
