[Springframework-developer] Ant 1.6.2

[Colin S. <col...@ex...>]

Ant 1.6.2 is out, and with it support for a forkmode="once" on the junit 
task, which allows ant to still fork for junit tests, but only once for 
the entire task (instead of for each testcase). Alternately, 
forkmode="perBatch" allows forking once per batch element.

This is pretty promising, since it could bring the time to run the test 
suite from ant down to a similar value to when running in an IDE, which 
is currently much faster.

I've tried to give it a go (making sure to remove the ant 1.6.1 in the 
lib dir, otherwise that will interfere), by adding forkmode="once" to 
the junit element in the tests target. It is currently breaking on 
SqlStateExceptionTranslatorTests, due to the initial context factory 
builder already being set. This should be resolvable by using a separate 
batch for that test, or some other strategy. I am curious however why 
this doesn't break in the IDE though.

I don't have time to play with this any longer, but will give it a go at 
some later date. If anybody feels like playing around with this 
themselves, please go ahead by all means.

Regards,
Colin
