OGNL 2.7.2 Released

Feb 1, 2008 in java, ognl

Not knowing where else to announce it I thought I should mention that version 2.7.2 of OGNL was quietly released yesterday and is now available via ibiblio. Special thanks to Toby Tmjee for his recent contributions and help on the project.

The number of issues being reported related to expression compilation seems to have gone way down - so it may tentatively be safe to say this feature is “becoming stable”.

The javacc grammar parser code was also re-generated for this recent release using some of the new improvements that Tom Copeland mentions here.

As I’ve not really done a good job posting updates about releases I’ll go ahead and dump the full 2.7 - 2.7.2 jira issue log here as well. The good majority of issues fixed have been related to the expression compiler work - but there is still a lot of good stuff in there that projects using it without expression compilation will still find very useful. (from straight up bug fixes to substantial performance / concurrency improvements and even full Java 5 support for generics and varargs)
