IC67705: JDBC PROGRAM SOMETIMES RAISES ERROR "INVALID CURSOR RECEIVED BY SQLEXEC" IN NON-ISTAR ENVIRONMENT

APAR status

• Closed as program error.

Error description

• When the session was aborted by "FORCE_DDL_EXEC" the jdbc
  program sometimes raises error "Invalid cursor received by
  sqlexec" in Non-ISTAR environment.
  
  The strange thing is the problem only happens in my stress test.
  I can not reproduce it when there is only one running program.
