Showing error for incorrectly closed tag fails

[Timo Arnivuo]

I had incorrectly closed crud.table tag. Opening tag had slash so closing tag threw exception.

#{crud.table fields:['content', 'post', 'author'] /}
 #{crud.custom 'content'}
  <a href="@{Comments.show(object.id)}">
   ${object.content.length() > 50 ? object.content[0..50] + '…' : object.content}
  </a>
 #{/crud.custom}
 #{/crud.table}

 Unfortunately 500.html template fails to present this exception with IndexOutOfBoundsException

Template execution error (In {play}/framework/templates/tags/500.html around line 101)
Execution error occured in template {play}/framework/templates/tags/500.html. Exception raised was IndexOutOfBoundsException : toIndex = 26.

This is really minor issue as initial reason can be seen from log.
