svn commit: r731651 - in /tomcat/trunk/java/org/apache/jasper/compiler: ImplicitTagLibraryInfo.java JspUtil.java ParserController.java TagFileProcessor.java TagLibraryInfoImpl.java

Author: markt
Date: Mon Jan  5 11:20:11 2009
New Revision: 731651

URL: http://svn.apache.org/viewvc?rev=731651&view=rev
Log:
Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=46471
Use the URL of the JAR as well as the path within the JAR to identify a tag file to keep tag file definitions unique.
