As John notes, we did try using jarjar to repackage, and there are several cases where it doesn't help. In particular, see r4419 where Lex and I added it and r4681 when it was pulled to fix problems in HostedMode. (In addition to the HostedMode bits, swt has native language issues and tapestry has dynamic construction issues; you can look at r4419 for the exceptions Lex and I started with. I don't recall the HostedMode problems in particular... That said, commons-collection wasn't a problem case. For Nocolas' sanity *right now*, and with a specific collision point, I'd suggest that he post-process his GWT jars in one of two ways: 1. you could run jarjar yourself, for commons-collection, or 2. you could excise those classes from "our" jar, and just use "yours" on your classpath. Obviously, that's a configuration we haven't tested (really, so's the first), but I mostly trust Apache. Still, YMMV.
