[armedbear-devel] Catching CL errors in java

[Alessio Stalla]

Short story: if you call into Lisp using the JSR-223 API, conditions
are automatically rethrown as Java exceptions.

Long story: the way this is implemented is by binding *debugger-hook*
to an internal, probably undocumented function, that already does what
you want. It is called sys::%debugger-hook-function.
