"read" intent methods on shared java.util.Calendar/GregorianCalender can throw
UnlockedSharedObjectException
------------------------------------------------------------------------------------------------------------
Key: CDV-606
URL: https://jira.terracotta.org/jira//browse/CDV-606
Project: Community Development
Issue Type: New Feature
Components: Byte Code Transform
Affects Versions: 2.5.1
Reporter: Tim Eck
Assignee: Issue Review Board
It is easy to recreate this -- Share a virgin instance of GregorianCalendar
(one that is newly constructed, but for which no methods have been called) and
call get(YEAR) on it.
One thought for resolving this issue, is to have an applicator call call
Calendar.complete() when new instances are become shared. A review of the
internal state for like issues need to be done before this approach should be
implemented.
This is the [unexpected] UnlockedSharedObjectException you will see:
Caused by Thread: http-0.0.0.0-8080-1 in VM(0)
Shared Object Type: [I
