[Jython-dev] Catching java.lang.OutOfMemoryError

[Ype K. <yk...@xs...>]

Dear jtyhon developers,

I had google look for some earlier discussion on this subject
as I vaguely recall java and jython exceptions being discussed
not too long ago. However I could not find anything specific
on my problem.

I have roughly the following situation:

import java
somejythonfile = ....

try:
    execfile(somejythonfile)
except SomePythonDeclaredException, ke:
    nicelyCaught = ke
except java.lang.OutOfMemoryError, oome:
    neverCaught = oome
except Exception, e:
    someTimesCaught = e
except:
    # some releases ago, I tried this to catch an occasional
    # internal compiler error, and then it never occurred again...
    ei = sys.exc_info
    ...


My problem is that java.lang.OutOfMemoryError is never caught,
even when 'somejythonfile' causes it.
I also tried to catch java.lang.Throwable, but it flew along as well.

Do I have to go through some java code:

try {
    org.python.core.__builtin__.execfile(somejythonfile);
    // or whatever it is called in java
} catch (java.lang.OutOfMemoryException oome) {
    throw org.python.core.PyException(oome.toString());
}

or can it be done directly in jython?

I realize that running out of memory is tricky business, but
it would be nice if catching this exception would be possible...

Thanks in advance,
Ype
