JRuby 1.0.3 is a minor release of our stable 1.0 branch. The fixes in
this
release include primarily obvious compatibility issues that we felt were
low risk. We periodically push out point releases to continue supporting
production users of JRuby 1.0.x.

Highlights:

  • Signal handling fixes involving mongrel
  • Smattering of smaller YAML problems fixed
  • 28 total issues resolved since JRuby 1.0.2

Probably better to ask this in a JRuby or Rails group.
Which is [email protected] and [email protected]

As Charles recently announced, any task in the current builds that is
now slower in JRuby compared to CRuby should now be treated as a bug.
If you have a test case that show this, make a report.
Indeed. I should also note that we have two branches of JRuby:

1.0.x - A stable release line where our primary focus has been decent
compatibility with Ruby
1.1 - Soon to have beta 2 out which has an additional focus on improving
performance

If anything is slower in 1.1 than in MRI (C impl of Ruby) we want to
know about it. In under a week JRuby 1.1b2 will be out. Try things out
and report issues. We want 1.1 to be a stellar release.

“Getting Started” and “Limitations” to the right should answer most
things.

Forgot your manners?

Sad,

I get a lot of requests to write personalized responses to people who
clearly haven’t made any effort, and hence are obviously too lazy to use
the information. This was the 2nd in an hour. If someone has special
needs
and can’t find existing information or decide whether the software
suits,
I’m always cheerfully willing to help. But this sort of lazy-student
question deserves scorn. As if one click by them is more costly than
someone else composing a customized response… who’s lacking manners in
this case?

Even so, that probably doesn’t trump MINASWAN on this list, though,
right?

You’re right, I was uncivil. I’ll try to be better. Sorry folk.
