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.
