A DESCRIPTION OF THE PROBLEM :
XMLEncoder does not store arrays of things
in beans persisted with it. The example below shows
a string array; although, the problem happens
with other types of arrays.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. run the sample code below
2.
3.

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expect string array to be written and
restored

This bug can be reproduced always.
