Default ThreadPool Size

[Isuru Suriarachchi <is...@gmail.com>]

Hi all,

Currently the default max thread pool size is set to Integer.MAX_VALUE. Due
to this, there can be situations where a huge number of threads created when
lot of non blocking requests are done by a client. To test this, I just
wrote a simple service client which continuously fire and forget one way
requests in a non blocking manner (using following parameter).

options.setProperty(MessageContext.CLIENT_API_NON_BLOCKING, Boolean.TRUE);

When I got a thread dump after some time, there where about 20000 "Axis2
Task" threads created. Sometimes the client hangs due to this reason.

Then I set the maxPoolSize in ThreadPool to 100 and did the same test again.
then there were only few (less than 10) "Axis2 Task" threads in the thread
dump and the client ran smoothly.

So shall we fix this and set the default value to something like 100?

Thanks,
~Isuru
