No, the exit will not get called again after conversion of the JCL.    But you
can protect the ability to change the class via operator commands or
products like SDSF with external security (RACF/ACF2/Top Secret).

For example, in the OPERCMDS class you would protect 

JES2.MODIFY.BAT 

See the JES2 Init and Tuning for more details.
