--------------------------------
Duplicate of POOL-250.
> wish to Commons Pool 2 works with Android environment
> -----------------------------------------------------
>
> Key: POOL-251
> URL: https://issues.apache.org/jira/browse/POOL-251
> Project: Commons Pool
> Issue Type: Wish
> Affects Versions: 2.1
> Environment: Android
> Reporter: Jungtaek Lim
>
> 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
