-----------------------------------------

             Summary: dbcp2 datasource lock contention on createDataSource + illogical locking
                 Key: TOMEE-1832
                 URL: https://issues.apache.org/jira/browse/TOMEE-1832
             Project: TomEE
          Issue Type: Bug
            Reporter: Romain Manni-Bucau
            Assignee: Romain Manni-Bucau
             Fix For: 7.0.1


We extend dbcp(2) datasource to add some custom features like password ciphering etc...

We need to ensure locking is consistent (ie we dont use our own locking when parent uses synchronized)
+ createDataSource should absolutely avoid locking as much as possible at runtime (as its
parent)

Side note: normally it is not a high requirement to synchronize getters/setters (parent doesnt)
but worse case it doesn't hurt there if we want to do runtime modification later
