Description of problem:
If a jsp includes itself, the incremental compiler will try to process
it causing a JVM core dump.

Version-Release number of selected component (if applicable):
eclipse-lomboz-3.0-7

How reproducible:
always

Steps to Reproduce:
1. Create a new J2EE project with a web module (choose Jonas 1.4.x server)
2. Open up the default "index.jsp"
3. add the line "<%@ include file="index.jsp" %>
4. Save the file
  
Actual results:
JVM core dumps

Expected results:
Lomboz should report an error.

Additional info:
This may seem pointless as recursively including a jsp in itself is a
bad idea in the first place. However, if a user accidentally types the
wrong jsp name, the jvm will crash and the workspace can only be
recovered by manually removeing the recursive include from the jsp.
(eclipse will cause JVM crash every time the file is [re]opened)
