Hello all, I tried to find in the code where you are using guava and could not find it so I do not know if it is added as a module for a specific reason, it is just a leftover or it is me that I just do not know how to grep code :) I was reading the jenkins mailing list and apparently there is a memory leak in guava r06 that was fixed in r09 (although the latest version is r10) I thought you might want to take a look at that. http://code.google.com/p/guava-libraries/issues/detail?id=573&can=1&a... Regards -- Those who do not understand Unix are condemned to reinvent it, poorly. Any sufficiently recent Microsoft OS contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Unix.
