[jira] Commented: (VELOCITY-709) String literal "\\" parses incorrectly

["Steve Ragle (JIRA)" <de...@velocity.apache.org>]

    [ https://issues.apache.org/jira/browse/VELOCITY-709?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12802400#action_12802400 ] 

Steve Ragle commented on VELOCITY-709:
--------------------------------------

This breaks a critical template for us (which is highly customized by many of our customers), which means we can't use 1.6 at all unless this is fixed.  That's a shame because I was looking forward to taking advantage of several 1.6 changes and features.

> Given the following VTL:
> #set($var = "\\" )
> #set($var2 = "${var}")
> results in the following parse error:
> Encountered "${" at test.vm[line 2, column 15]
> Was expecting one of:
>     <RPAREN> ...
>      ...
> the problem is that when parsing the string literal "\\" the second double quote is escaped.  This was actually a bug that was introduced in 1.6.x, but I don't think we necessarily need to fix it in that branch.
