Could you attach project in which this is happening?
Created attachment 182872 [details] patch Based on above stacktrace, i was able to recreate this problem of NPE(but no freeze).It is caused by tld with structure similar to: <?xml version="1.0" encoding="UTF-8"?> <taglib xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd" version="2.0"> <shortname><child></child></shortname> <tlib-version>1.0</tlib-version> </taglib> Notice '<child></child>' inside shortname.Now shortname will be returned as empty string.
Changes checked in.
