What is the value of the request-processing thread-count attribute in
domain.xml? By default is 5, but you seems to either increased the
value. Also how many http-listener do you have. Unfortunalty, the
request-processing thread-count applies to all http-listener, so if you
have x http-listener, you gonna ends up with x * thread-count blocked
thread.
I suspect your CPU spinning could be related to issue:

Is GlassFish servicing https requests?
