Mark Thomas resolved POOL-292.
------------------------------
Resolution: Pending Closed
> ClassNotFoundException: org.apache.commons.pool2.impl.DefaultEvictionPolicy
> ---------------------------------------------------------------------------
>
> Key: POOL-292
> URL: https://issues.apache.org/jira/browse/POOL-292
> Project: Commons Pool
> Issue Type: Bug
> Affects Versions: 2.3
> Environment: Apache Karaf OSGi
> Reporter: Narayanan Harihara
> Labels: OSGi,, classnotfoundexception
> Fix For: 2.4
>
>
> Here is my application structure:
> myapplication-bundle(uses mybatis) --> datasource-bundle (uses
> commons-dbcp2) --> commons-pool2 bundle.
> With this structure, all the datasource API information are hidden from my
> application and only javax.sql.DataSource is exported from the
> datasource-bundle. So I do not have OSGi import package for
> org.apache.commons.pool2.impl in my application.
> But on version 2.3 of commons-pool2, the method
> org.apache.commons.pool2.impl.BaseGenericObjectPool.setEvictionPolicyClassName
> is using Thread.currentThread().getContextClassLoader() to load
> EvicationPolicy class, which means it is using the class loader of
> myapplication to load org.apache.commons.pool2.impl.DefaultEvictionPolicy
> class. Since I do not have that in myapplication-bundle's OSGi
> Import-Package, I get a ClassNotFound exception.
> This issue did not happen in commons-pool2 version 2.2 because, it did not
> use the current thread's class loader to instantiate the eviction policy. Due
> to this, I am kinda forced to use 2.2 version in my environment and i would
> like to stay on the latest version due to all the bug fixes with concurrency.
> Any help would be really appreciated.
