Note the "null"; That is returned by findMapping() to getJspLineErrors() in jasper/src/share/org/apache/jasper/compiler/Compiler.java Given that null is a possible result for findMapping(), getJspLineErrors() should check for it before using the value. But I expect findMapping() was actually supposed to find some mapping for this line. I haven't had the time to look into this further.
