> as part of improved testing, i thought it would be a good idea to make the build (ant
test) more friendly
> to working under apache harmony.
> i'm not suggesting we de-optimize code for sun jvms or anything crazy like that, only
use it as a tool.
> for example:
> * bugs in tests/code: for example i found a test that expected ArrayIOOBE 
>   when really the javadoc contract for the method is just IOOBE... it just happens to
>   pass always on sun jvm because thats the implementation it always throws.
> * better reproduction of bugs: for example [2 months out of the year|http://en.wikipedia.org/wiki/Unusual_software_bug#Phase_of_the_Moon_bug]
>   it seems TestQueryParser fails with thai locale in a difficult-to-reproduce way.
>   but i *always* get similar failures like this with harmony for this test class.
> * better stability and portability: we should try (if reasonable) to avoid depending
>   upon internal details. the same kinds of things that fail in harmony might suddenly
>   fail in a future sun jdk. because its such a different impl, it brings out a lot of
interesting stuff.
> at the moment there are currently a lot of failures, I think a lot might be caused by
this: http://permalink.gmane.org/gmane.comp.java.harmony.devel/39484
