Matthew Broadhead commented on TOMEE-1743:
------------------------------------------
this is still a problem for me also. during development i keep getting 500
internal server error. restarting the server always solves the problem but it
is very time consuming. not sure what could cause it to happen but it seems to
be during a rebuild following any code change. it has happened to me
occasionally in production also
