New Revision: 960283
URL: http://svn.apache.org/viewvc?rev=960283&view=rev
Log:
Fix Bug 49528 - HttpServletRequest.isAsyncStarted() returns false when a
Runnable is started
Add isDebugEnabled statements.
Todo: Why we doesn't start directly a container thread with
asyncContext.start()?
Currently we start user runnable as an internal forward.
