Fay Wang updated OPENJPA-1352:
------------------------------
Attachment: OPENJPA-1352.patch
Although Arrays.asList returns a List object, its class is Arrays.ArrayList.
This is a static private inner class and can only be constructed from within
Arrays. During merge/persist, openjpa needs to construct a proxyCollection by
instantiating a new List object based on the class type of the original
collection. This attempt fails because Arrays.ArrayList can not be
loaded/constructed from outside Arrays.
The attached patch is to return null value if the class can not be loaded
instead of throwing the exception. A test case will be attached later.
> Merge fails if an entity has an element collection which is contructed using
> Arrays.asList
