Juergen Hoeller e4bd1344e2 Set and reset shared isolation value within synchronized transaction begin
Since EclipseLink applies a custom transaction isolation value to its shared DatabasePlatform instance, we need to immediately restore the original value after the current value got picked up for JDBC Connection access inside of EclipseLink. In order to not interfere with concurrent transactions, we need to use synchronization around the transaction begin sequence in such a case.
