tracker issue : CF-4095231

Problem Description:

After performing an app restart via application.stop() we usually get a couple of the below from pages using cfimage action=captcha. I know this is happening at least after all code within the onApplicationStart() method has run aswe have the time dumped at the start and end of the onApplicationStart() method.

Steps to Reproduce:

Call application.stop() while under moderate load and the odd page will throw this error

Actual Result:

NullPointerException

Expected Result:

All works

Any Workarounds:

Timings:

onApplicationStart Start {ts '2015-11-30 14:33:48'} 
onApplicationStart End {ts '2015-11-30 14:34:13'}
Error Timestamp: {ts '2015-11-30 14:34:18'}
