Browse to the sourcecode of v8.0.20 of tomcat here:
https://svn.apache.org/viewvc/tomcat/tc8.0.x/tags/TOMCAT_8_0_20/java/org/apache/jasper/JspCompilationContext.java?view=markup
The lines you want look like this:
535 public TldResourcePath getTldResourcePath(String uri) {
536 return getOptions().getTldCache().getTldResourcePath(uri);
537 }
Obviously either getOptions() or getTldCache() is returning null.
Reverse engineer the source to find out which, or stop the code in a debugger.
