Description Naohito Sato 2002-11-10 05:16:20 UTC 
In case a blank tag name exists in TLD like follows,

  <tag>
    <name/>
    <tag-class>foo.BarTag</tag-class>
  </tag>

Jasper jspc reports

% $JASPER_HOME/bin/jasper.bat jspc

error:null

To found this reason, I took few hours.
I want Jasper jspc to report more details!

This is an enhancement request, not a bug.

Just tested this with 7.0.x and with if deploying a web application with such a TLD full details are provided.

With JspC, the NPE from TagLibraryInfo did mask the problem. I have made that method more robust when it comes to handling nulls.
