Created an attachment (id=23078)
 --> (https://issues.apache.org/bugzilla/attachment.cgi?id=23078)
webapp that reproduces the issue when compiled by JspC

To reproduce the issue:

The following recipe is for Eclipse IDE project for TC 6.0.

1. In your project folder create the following subdirectory and two
subdirectories in it:
 bug37084
   /output
   /source

2. Unzip the war file into bug37084/source

3. Create the following Run configuration:
type: Java Application
Main class: org.apache.jasper.JspC
Arguments / Program arguments:  -uriroot bug37084\source -d bug37084\output

4. Run the application

5. A stacktrace is observed:

04.01.2009 10:06:30 org.apache.jasper.JspC processFile
SEVERE: ERROR-the file '\index.jsp' generated the following general exception:
java.lang.NullPointerException
        at sun.misc.URLClassPath$3.run(URLClassPath.java:323)
        at java.security.AccessController.doPrivileged(Native Method)
        at sun.misc.URLClassPath.getLoader(URLClassPath.java:320)
        at sun.misc.URLClassPath.getLoader(URLClassPath.java:297)
        at sun.misc.URLClassPath.getResource(URLClassPath.java:167)
        at java.net.URLClassLoader$1.run(URLClassLoader.java:192)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
        at
org.apache.jasper.servlet.JasperLoader.loadClass(JasperLoader.java:134)
...

6. Delete the generated files from bug37084/output

----------------------------------

The patch that I proposed above does not help. It just results in
java.lang.ClassNotFoundException being thrown instead of the NPE.
