Ex­tremeTrans­ac­tions 3.7.8

Th­ese are the re­lease notes for Ex­tremeTrans­ac­tions 3.7.8

87749: Sup­port short prop­er­ties in JDBC and JMS con­nec­tors

We've im­proved sup­port for short prop­er­ties that need to be con­vert­ed from a text/XML con­fig­u­ra­tion file.

75549: Op­ti­mize JTA per­for­mance

The UserTrans­ac­tionMan­ag­er class has a class-lev­el syn­chro­nized block used for init pur­pos­es. We've added ex­tra checks so this block is only ex­e­cut­ed if re­al­ly need­ed. This op­ti­mizes per­for­mance by lim­it­ing the num­ber of cas­es where threads will block each oth­er.

68724: Me­mory leak in the JDK's Ob­jec­tOut­putStream

We've added a re­set of the un­der­ly­ing Ob­jec­tOut­putStream for se­ri­al­ized log­ging, to avoid high mem­o­ry con­sump­tion when the JDK keeps point­ers to all pre­vi­ous­ly se­ri­al­ized ob­jects since the last check­point.

102827: Er­rors on close/delist lead to con­nec­tion pool ex­haus­tion

Fixed a crit­i­cal bug where er­rors on delist would cause con­nec­tion pool ex­haus­tion.
