[jira] Commented: (HARMONY-116) strange exec behaviour with harmony vme/classlib

    [ http://issues.apache.org/jira/browse/HARMONY-116?page=comments#action_12368528 ] 

Mark Hindess commented on HARMONY-116:
--------------------------------------

Looks good.  The build now completes with the Eclipse compiler.

Worse still if I create a matching executable in the basedir then that gets executed even if basedir is not in the path.  This would be a potential security problem in other situations.  I'll attach a test case shortly.

Fair comment.  I agree we should support those legacy systems too ;-)

At the moment, but I'm planning to try continuum on Harmony + IBM VME
again tomorrow.  It was previously failing with an error that looked
very much like another instance of this exec problem.

1) is doing what most people coming to the project will try first so
it's nice if it works.
2) is dog food.

Granted it's unlikely that we'd break 1 without breaking 2 but
diversity never a bad thing IMHO.

What do you mean at the moment? ;-)

So that's ant & the eclipse compiler running on Harmony classlib, but
presumably continuum itself is still running on a 'regular' jdk?

Why not just build using the latest classlib snapshot?  What does (1)
get you?   (mmm, dog food).

You're all a bunch of pessimists at the moment ;-)

Yes!  So now I'm hoping to change our internal builds to:

  1) Build with IBM jdk.
  2) Build with the resulting Harmony classlib + eclipse compiler + IBM VME

which might break things more often....

 Mark

Great, so are the classlib builds now running on the classlib code +
eclipse compiler + IBM VME?

Tim
