[jira] Commented: (VELOCITY-216) Thread safety fault in Directives when Template caching on

    [ http://issues.apache.org/jira/browse/VELOCITY-216?page=comments#action_12329770 ] 

Will Glass-Husain commented on VELOCITY-216:
--------------------------------------------

Geoffrey - any thoughts on this?  We're looking at bugs to fix before the 1.5 release.  We may close this if we can't figure out the specific problem with #foreach.  Thanks.

> When the template caching is on, concurrent thread may used at the same time 
> the same compiled template.
> As Directives are not designed to be stateless it may produce funny effect.
> Example: #foreach
> T1:     #foreach    ...    |    ...    |    ...    |    ...    |   
>            c=0            c=1   c=0   c=1   c=2   c=3   c=4 
> T2:                           #foreach...    |    ...    |
