Thomas Mortagne commented on VELOCITY-900:
------------------------------------------
This is probably because Velocity thinks you are trying to call the directive
"end__" since _ is valid in a directive name. You can workaround it by using
{{#{end}}}.
> Velocity.evalute thows an exception if the next char after a keyword is '_'

> Reporter: Alto
> Priority: Major
>
> If I try to evalute the folling template "CONSTRAINT
> DF_#if(${archiveTableTemplate})${archiveTableTemplate}#else${table}#end__${column}"
> an exception is thrown.
> Velocity.evaluate(myContext, myStringWriter, "LOG", template); = >Exception
> occurred in target VM: Encountered "<EOF>" at LOG[line 1, column 93]
> Was expecting one of:
> "(" ...
> ")" ...
> <ESCAPE_DIRECTIVE> ...
> "]]#" ...
> <WHITESPACE> ...
> <NEWLINE> ...
> <SUFFIX> ...
> <STRING_LITERAL> ...

> If I use the Template "CONSTRAINT
> DF_#if(${archiveTableTemplate})${archiveTableTemplate}#else${table}#end
> __${column}" it works, but the result is wrong. Blank after replacement.
