Attribute doesn't exist in class: NullPointerException

Runtime Error:

java.lang.NullPointerException
at
net.sf.maventaglib.checker.TldChecker.checkAttribute
(TldChecker.java:256)
.......

I figured out the issue. When encountering an attribute
with a name that doesn't exist as a property in the tag-
class it throws this error.

To quickly recreate this issue simply add an attribute to
an arbitrary tag element in an appropriate tld. ie.
<attribute>
<name>deleteMe</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
<type>java.lang.String</type>
</attribute>

and run maven taglib:validate\

thanks! plugin rules!
