William Walsh commented on AXIS2-5110:
--------------------------------------

Andreas,  Thanks for he confirmation on that - that's what I thought.  So, it 
doesn't sound like the workaround in AXIS2-4263 is applicable in this case.  So 
far the only workable solution I've found are the code changes mentioned here.  
Do you have any other ideas?


> Compatibility with WebSphere Application Server on z/OS
> -------------------------------------------------------
>
>                 Key: AXIS2-5110
>                 URL: https://issues.apache.org/jira/browse/AXIS2-5110
>             Project: Axis2
>          Issue Type: Improvement
>          Components: kernel
>    Affects Versions: 1.5.1
>         Environment: WebSphere on z/OS V7
>            Reporter: William Walsh
>            Priority: Minor
>
> 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?
