One solution would be to always set the loops for the validations that
install one of these pipes. That could have potential performance
impact, but it would be no worse than the validation sequences that
already set the loops every time so I don't think it would be serious,
or even measurable.
Hi Jim,
I'm trying this approach.
Basically, I just set the loops to null now in invalidate and validate
them back in validatePipe:
http://cr.openjdk.java.net/~neugens/100068/webrev.03/
What I do is to get valid Loops when we call getTextPipe, but other than
that, the behavior is basically unchanged. I tried with various
applications, including NetBeans, the Java2D demo and the FontTest app,
playing around with the text configurations (AA, LCD, size, Glyphs etc..
even output to a PNG file) and looks good, but I may miss something of
course.
I moved to a 64 bit machine, I don't think this makes any difference in
this case, but maybe it's a good thing to say.
I would like to see a method in the pipelines that does something like:
boolean mustInitialiseLoopsBecauseWeReallyWantToUseThemGranted()
or so, that we may call at the end of the validatePipe method, but when
I tried this I got a funny StackOverflowException, maybe I did something
wrong, but looks like it's not so easy to change this code and still
make it behave correctly, so I would like to go deeper in this issue
even if you think we can close the bug (of course if the proposed fix is
evaluated as complete).
Cheers,
Mario
