I will happily share it (contribute it), if someone interested > when it's finished. interested, yes there are unresolved policy questions about code with LGPL dependencies at apache ATM but i hope that these will be resolved before the end of the year. even if these aren't resolved in time, it's be great if you'd either grant a license to apache for eventual inclusion or start a project offshore (googlecode is pretty good). an alternative strategy would be to indirectly create a hibernate implementation via JPA. apache has a good JDO backed JPA implementation. at most, the hibernate specific deployment would have to be kept offshore but the vast majority of the code could be committed to JAMES right away. (i'm interested in JDO and would be much more likely to contribute to a OpenJPA implementation than to a plain hibernate one. the OpenJPA team is also very friendly so i'm sure that they'd be happy to help out with architecture.) > I have some question about the current IMAP code in the trunk.
