Can you upgrade to the newest version of Jruby-rack (0.9.5)? IF so
does the problem still exist? I remember reading a post on Nick
Sieger’s blog about some bug in Jruby-Rack and the latest Rails and
that upgrading to 0.9.5 should fix it.

Yep, that bug was definitely solved in JRuby-Rack 0.95

Thanks! I was using the old warbler gem (0.9.13) which included the old
JRuby-Rack 0.9.4 …updating to the newest i solved. Then i updated also
the warbler to 0.9.14 version which also have the newest jruby jars
(1.3.1) and i’ve remaked the .war.
Another important step was to copy jdbc jars in the app lib, now it
works!
…but only in production mode, in develop mode i get a thread error,
this is the message:

as if every thread remained active, the creation of the new one generate
the error, for example: if the minimum number of threads is 2, the third
raise that error

i’ve found something about it

I’ve also pushed a 0.9.6 snapshot to 1 so that others won’t have to
build it.
