Subject: CSPACE-5129: Cleaned up repository session managment and transaction management when... 
X-Git-Url: https://git.aero2k.de/?a=commitdiff_plain;h=db3a378a863161c64c5f027c99e66bd0d3f4d796;p=tmp%2Fjakarta-migration.git

CSPACE-5129: Cleaned up repository session managment and transaction management when making resource to resource method calls.  The ServiceContext is now able to keep track of RepositorySession instances and keeps reference counts on them.  Only when the reference count drops to 0 is it released and the transaction closed.
