>                 Key: POOL-256
>                 URL: https://issues.apache.org/jira/browse/POOL-256
>             Project: Commons Pool
>          Issue Type: Task
>         Environment: Android
>            Reporter: Jungtaek Lim
>            Priority: Minor
>
> This issue starts at https://github.com/xetorthio/jedis/issues/538.
> Jedis - Java Redis Client - seems to stop working with Android at that time Jedis changes
Common Pool version from 1.6 to 2.0.
> I found Commons Pool 2 uses jmx, which Android cannot support.
> I believe it makes error with class loading, so disabling jmx cannot resolve this issue.
> {code}
> public BaseGenericObjectPool(BaseObjectPoolConfig config,
>             String jmxNameBase, String jmxNamePrefix) {
>         if (config.getJmxEnabled()) {
>             this.oname = jmxRegister(jmxNameBase, jmxNamePrefix);
>         } else {
>             this.oname = null;
>         }
> ...
> {code}
> {code}
>     private ObjectName jmxRegister(String jmxNameBase, String jmxNamePrefix) {
>         ObjectName objectName = null;
>         MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
>         int i = 1;
> ...
> {code}
> Please double check Commons Pool 2 is not working with Android.
> And if it's not working, I wish you to make Commons Pool 2 jmx usage selectable.
> ps. error message follows
