Re: Jython 2.7 standalone "lite" ?

Jason Sachs
Has there been any recent work on making a Jython 2.7 standalone "lite" package, with a smaller .jar size? (2.5.3 was 13.7M, 2.7 is 35.3M)

Some of us don't need the unicodedata module or the functionality in bouncycastle or netty, and it would be nice to be able to use Jython without these features if it reduces the .jar footprint.

Yes, sorry about that. We are focused on correctness first, then we will go
and trim down in subsequent 2.7.x releases, where x > 0. A huge chunk of
that additional bloat is supporting unicodedata and the corresponding ICU4J
jar we now use.

It should be a straightforward matter of programming to remove this ICU4J
dependency. Possibly this and other optimizations, especially startup time,
would be suitable for a Google Summer of Code student, given that we are
planning to participate this summer.
