Description

In using Axis2 with WebSphere across multiple platforms we have found that once we invoked a web service against Axis2 on WebSphere for z/OS that the application server would not shutdown properly. (The architecture on z/OS is very different than other platforms - it uses a number of address spaces to host WebSphere and the control and servant address spaces would not terminate.) We asked IBM about this and it has to do with differences in how the JVM is implemented and started by WebSphere on z/OS. The long and the short of this is that Timer threads must be defined as daemon to allow WebSphere to terminate properly on z/OS.

I'd like to propose a patch for this and would like to know/confirm:
Are these classes where I saw non-daemon threads created the appropriate places for change?
/org/apache/axis2/util/threadpool/ThreadPool.java
/org/apache/axis2/util/threadpool/DefaultThreadFactory.java
/org/apache/axis2/transport/http/server/DefaultThreadFactory.java

I would propose adding conditional code to force daemon threads when running on z/OS:
if (System.getProperty("os.name").equals("z/OS")
Would this be appropriate, or do you feel the check needs to be more explicit; also checking for WebSphere?
