---------------------------------------
Summary: CopyHelper.copy will fail on java 16 and later when
copying instances of Clonable
Key: GEODE-9469
URL: https://issues.apache.org/jira/browse/GEODE-9469
Project: Geode
Issue Type: Bug
Components: core
Reporter: Darrel Schneider
CopyHelper.copy is an API that allows geode users to make copies of objects. It
is also used internally by a number of geode features. The copy-on-read region
attribute is one example. If the object being copied is an instance of
Cloneable then on java 16, copy will throw a RuntimeException which is an
instance of java.lang.reflect.InaccessibleObjectException.
The copy code tries to catch exceptions during the clone and instead use
serialization to make a copy but it does not catch RuntimeException which is
what java 16 throws from setAccessible. It would be pretty easy to fix this
exception handling.
The only work arounds are to not implement Cloneable or to start the jvm with
the command line option: --illegal-access=permit.
