-----------------------------------
> Hanging in jj_scan_token
> ------------------------
>
> Key: VELOCITY-775
> URL: https://issues.apache.org/jira/browse/VELOCITY-775
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Environment: Velocity 1.6.3
> Reporter: Dominik Stadler
> Assignee: Claude Brisson
> Priority: Major
> Fix For: 2.0
>
>
> 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:
> "1334671070@qtp-2060763463-85" prio=6 tid=0x00000000181c5800 nid=0x6004
