We are getting many reports of memory issues under u40 running appear with indy support. Some seem to go away with bigger heaps, but others are still eventually failing. This is a very high priority for us because we had hoped to release JRuby 1.7.5 with indy enabled (finally) and that may not be p

I've been trying our app/language runtime on 7u40 and we're seeing a similar increase needed in PermGen, and some increase needed to heap memory. Seem to have taken about a 10% performance hit on large application benchmarks as well, but I'd need to do some more runs to be really sure of that. On

I do not...but it appears to be tied to getting an OOM when inside lambda code. We now have a third-party report of the same issue. Because the internal error appears to nuke the original exception, we don't know for sure that this is memory-related, but the user did see *other* threads raise OOM
