Jungtaek Lim created POOL-255:
---------------------------------
Summary: Wish to Commons Pool 2 works with Android environment
Key: POOL-255
URL: https://issues.apache.org/jira/browse/POOL-255
Project: Commons Pool
Issue Type: Wish
Affects Versions: 2.0
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
