--------------------------------------
Summary: Mockito Unable to Mock
org.apache.geode.internal.cache.DiskRegion
Key: GEODE-10217
URL: https://issues.apache.org/jira/browse/GEODE-10217
Project: Geode
Issue Type: Bug
Components: core, tests
Reporter: Patrick Johnsn
Mokito cannot mock DiskRegion, DiskRegionView, and AbstractDiskRegion because
Byte Buddy could not instrument all classes within the mock's type hierarchy.

10:19:40 You are seeing this disclaimer because Mockito is configured to
create inlined mocks.
10:19:40 You can learn about inline mocks and their limitations under item
#39 of the Mockito class javadoc.

10:19:40 This problem should never occur for javac-compiled classes.
This problem has been observed for classes that are:
10:19:40 - Compiled by older versions of scalac
10:19:40 - Classes that are part of the Android distribution
