      Velocity 1.6.3

      Description

      I have the same issue as reported in VELOCITY-562, velocity hangs in method Parser.jj_scan_token(). I can reproduce it by running heavy load on my application for a few hours.

      Currently running 1.6.3, I looked at the issues fixed in 1.6.4, VELOCITY-718 seems not related, but I will now upgrade to 1.6.4 and see if the same happens again.

      The application is using velocity in up to 3 threads simultaneously, nothing is shared between threads, relevant stack traces from a thread dump are as follows, one thread is currently not inside velocity at all:
