New Revision: 1024229

URL: http://svn.apache.org/viewvc?rev=1024229&view=rev
Log:
Fix https://issues.apache.org/bugzilla/show_bug.cgi?id=49297
Enforce the rules in the JSP specification for parsing the attributes of custom and standard
actions that require that the attribute names are unique within an element and that there
is whitespace before the attribute name. The whitespace test can be disabled by setting the
system property <code>org.apache.jasper.compiler.Parser.STRICT_WHITESPACE</code>
to <code>false</code>

+        the attributes of custom and standard actions that require that
+        the attribute names are unique within an element and that there is
+        whitespace before the attribute name. The whitespace test can be

         <code>Enum.name()</code> rather than <code>Enum.toString()</code>
as
         required by the EL specification. (markt)
