Description Richard

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.

Given that the looping in the stack trace varies, this might be a legitimate overflow of the stack rather than a bug.

You can increase the size of the stack using -Xss option on Oracle VMs.
For example, ... -vmargs -Xss1M ...
