Description Richard CLA 2011-08-31 08:43:24 EDT 
Build Identifier: 20110615-0604

Very large mathematical expression in javascript causes a stack overflow.

Eclipse workspace becomes unusable until the file is removed using the file system.  Turning off all validation has no effect.

See attached log.

This is admittedly obscure.  This 'malicious' javascript is for browser security tests.



Reproducible: Always

Steps to Reproduce:
1. Create new Dynamic Web Project
2. Import the attached file "arith_100000.js" into the WebContent folder
3. Stack overflows.

Comment 3 Nitin Dahyabhai CLA 2011-08-31 09:11:10 EDT 
Given that the looping in the stack trace varies, this might be a legitimate overflow of the stack rather than a bug.
Comment 4 Olivier Thomann CLA 2011-08-31 12:27:12 EDT 
You can increase the size of the stack using -Xss option on Oracle VMs.
For example, ... -vmargs -Xss1M ...
