The following is the coding of the org.apache.jasper.compiler.TagLibraryInfoImpl.toString.

-------------------------------</pre>
LINRE129 is the place where the NullPointerException happened.
In my application,the element of <validator> is not defined in the TLD file.
as we know,if we don't want to test the TagLibrary,
there is no necessary to define the element of <validator>.
So,the phenomenon is a glassfish internal bug?
For this problem,Tomcat modified.
The following is modified details.
https://svn.apache.org/viewvc?view=revision&revision=306188
So, the LINRE129 should also be modified to
[print("tagLibraryValidator", "" + tagLibraryValidator, out);] in the glassfish?
