First, I want to say how much I really enjoy using RubyMine. It has really helped me write tighter code and increased my productivity. I especially love the debugging support.
We've recently started migrating our project to jruby 1.6.1 in 1.9 mode and noticed that the RM debugger no longer works under this configuration (works fine in 1.8 mode btw).
I googled the problem and found this bug:
This looks exactly like the problem I have. Since it was mentioned in the bug that this issue is fixed in RM 4 EAP I was wondering if we could expect that version to drop anytime soon?
