As you might have noticed, if you are reading the JIRA messages on the
commits list, I've been looking at the error case behaviour of
constructors.  (In fact, I've written a Perl script to generate a
program to creates several thousand test cases from the constructor
specification in a japi file.  I'll probably extend it to test other
static methods when I have a spare minute.)

I'm wondering how far we should try to match the behaviour of the
reference implementation.  For instance, I've been submitting fixes
for a number of cases of incorrect exceptions being thrown and I think
they are worth fixing, but then I came across this one:

  j.io.RandomAccessFile((j.l.String)null,""): # i.e. null filename, empty mode

the RI throws j.l.IllegalArgumentException because it checks the mode
first but we throw a NullPointerException because we check the file
first.

Does it matter?  Should we be matching behaviour?

Wasn't this the topic for a fairly recent discussion on the list ? If I can recall correctly, the consensus seemed to be YES it matters and YES we should be matching behaviour.

And if that wasn't the consensus then it should have been ;-)

Best regards,
George
