    custom component: porting from lc 8.0 to lc 8.2

      hello

       

      i developed a java pojo custom component for lc 8.0, essentially it connected to a db and returned a complex object. Now the environment has been upgraded to lc 8.2 . I've loaded my processes (which include my custom component) on the new environment. When i start the process , my component reaches the finally block where i've logged the db connections closing. Immediatly after the system crushes with the following error(i haven't added the whole stack trace because its huge):

      After that jboss get stucked, printing exceptions every 2 minutes, and i need to stop and restart it. I don't see anything wrong with my code: i get the datasource object, i get a coonettin from it, make my queries/updates and finally i close the connection.

      googling i've found this might be due to datasource item being local-tx-datasource instead of xa-datasource, but all datasources are of this kind.

       

      Any hint about this problem will be greatly appreciated

       

      thank you in advance
