NullPointerException instead of error message when running JspC





------- Additional Comments From cokelley@alumni.princeton.edu  2003-06-03 17:32 -------
This bug is especially serious since it can hide errors that are not 
reproducible when precompilation is off. For instance, I added a taglib to my 
project. Without precompilation, I get no errors. When I precompile, I get an 
NPE with no explanation.

After I realized that the taglib was the problem, I added another step to my 
build process (to pre-pre-compile the tags). However, since some time had 
passed since I added the tags, it wasn't obvious.

In other words, this NPE hides errors that are difficult to fix (the "don't 
precompile" workaround isn't always available) and makes precompilation risky 
from a development standpoint.
