------------------------------------
Summary: org.apache.mesos.Log isn't mockable
Key: MESOS-796
URL: https://issues.apache.org/jira/browse/MESOS-796
Project: Mesos
Issue Type: Bug
Components: java-api
Reporter: Suman Karumuri
Currently, the Log class (org.apache.mesos.Log) in the Java API has a static
initializer that calls MesosNativeLibrary.load(). This static initialization
causes issues when mocking this class.
Per JLS, using the Class name shouldn't trigger the static initialization.
However, the ClassProxy in EasyMock performs some reflection tricks which
trigger the static initializer. Since the static initializer needs a native
library which would be otherwise be linked dynamically in it's path, it makes
our unit tests flaky.
After considering a few possibilities, the cleanest solution seems to be
(a) Make org.apache.mesos.Log an interface so users using the Java-API can mock
the interface. or
(b) Add a new interface that org.apache.mesos.Log implements, which the clients
can use for mocking.
