svn commit: r1501266 - in /tomcat/trunk: java/javax/el/MapELResolver.java
test/javax/el/TestMapELResolver.java
Author: violetagg
Date: Tue Jul 9 13:59:07 2013
New Revision: 1501266
URL: http://svn.apache.org/r1501266
Log:
javax.el.MapELResolver:
1. According to javadoc when creating FeatureDescriptors
- ShortDescription must be empty string
- ELResolver.RESOLVABLE_AT_DESIGN_TIME must be TRUE
2. Unit tests are added
