Summary: Tapestry Spec Editor Unusable on Mac OS X

Initial Comment:
On OS X, I am finding that the Tapestry Spec Editor spends most of 
it's time in the rainbow pinwheel (the Mac equivalent of the 
hourglass), or flashing the black and white pinwheel, quickly, 
purposelessly. When not stuck in the pinwheel, typing is so slow, I'm 
having flashbacks of my 2400 baud modem.

All of Spindle seems to work flawlessly except the Spec Editor, 
which does work, it is just painful. Every key press causes cursor 
spasms and a great delay. I have given Eclipse from 250Mb to 1 gig 
of memory and none of that makes a difference.

For now, I'm simply opening all my jwc and page specs in the text 
editor. They are decorated with the red x to mark errors and the 
problems view gets updated just fine, but I neither get syntax 
highlighting nor completions.

I am using Eclipse 3.0.1 and Spindle 3.1.24. I am currently on Tiger, 
but I had this same problem on Panther. I have had this problem 
since moving to a Mac. I have never seen this issue on Windows.

I am attaching some of my .log that looks potentially relevant.

well waddaya know... I think I fixed it. The outline was
updating on every keystroke (no problem on windows) but in
the next release (3.2.4) the updating of the outline will
occur in the reconciler thread.

That thread only starts after you stop typing for 500ms or
so. So, while the hit will be there, it will not happen
nearly as often.

I should have mentioned that I had tried that already, but I
tried it again.

The outline view appears to have to effect on the problem.

Try something for me...

Close all Spindle spec editor and open the spec editor on
one file.

Close the outline view.

Problem goes away?

Spindle 3.2.2's Spec and HTML editors on Eclipse 3.1.0
(Build id: I20050627-1435) on OS/X 10.4.2 are faster than
they were. The spastic pinwheel is now only the black and
white one and not the rainbow pinwheel. I can still easily
out type the UI and watch my letters appear, but they appear
faster. It does not completely freeze. However, it is still
not usable.

Worse still for debugging, I have nothing from Spindle in
the stack trace. My log is free of spindle messages.

XMLBuddy gets decorated when there are errors, but I have no
autocomplete. Small price to pay, I still get the
compilation errors. Spindle still rules.

Someday, I'll have time to help diagnose this further.

Looking at the original stack trace attached to this bug I
think that recent changes will have address at least some of
the problem.

I would implore that a Mac user try out Spindle 3.2.2 (about
to be released)  and see if the situation has improved at
all. If not, pls attach a new stack trace as the line
numbers in the old one don't match the current code.

Thanks!

The new stack trace is a Xerces conflict. A description of
the problem (in one particular case - RSA)  is found here:

http://jroller.com/page/glongman?entry=spindle_breaks_in_rsa_6

The question is where is Xerces getting into Java's root
classloader? Sun VMs ship with crimson so no problem unless
users preempt that using the endorsed jar method. IBM JRE's
appear to screw up Spindle because they ship with Xerces by
default. I don't own a Mac so I can't tell what the cause is
in this case.

I confirm this is still an issue. I am experimenting the same symptoms 
on Mac OS X.4 running Eclipse 3.1 and Spindle 3.2.0. Curiously, the log 
error messages no longer are those reported by Galen.
Here's mine :

Although I can't reproduce this on a PC, I have examined the
errors and made some changes. If I were you I would try out
3.1.27 when it appears and report you experiences here.
