Use x'4040404040404040' instead x'0000000000000000' in field JVM SERVER

CICS is initializing and does SYSTEM AUTOINSTALL for LE modules.
One second later a PLTPI program deletes some of these modules like, CEEEV000, CEEEV001, CEEEV002, CEEEV007, CEEEV008, CEEEV009,
CEEEV012, CEEEV013, CEEEV014, CEEEV015, CEEEV016, CEEEV017, IBMBPSMA, IBMBPSLA.
All these programs have x'0000000000000000' and not x'4040404040404040' in the JVM SERVER field in the DFBSTUP output. In the dump we see no PPTE entries for those programs.
This problem appears because CICS is in the Startup process and AUTOINSTALLs these programs. Before the initialization for these programs has completed, they have been
deleted by a PLT program. After that the following Messages appear and document that CICS is up and running now.
DFHSI8434I Control returned from PLT programs during the third stage of initialization.
DFHSI1517 Control is being given to CICS.
DFHSO0101I Sockets domain initialization has ended.
DFHDH0101I Document domain initialization has ended.
DFHSJ0102I SJ domain initialization has ended.
This is a timing problem, recommended Mr. Reis to modify the PLT program and remove the DELETE commands, if this is a problem for anybody.

    There is a bug in the unsolicited stats record for program definitions (which are produced when a program definition is discarded) in that the jvmserver field was not being set to blanks for non java programs and to the name of the jvmserver for java programs. This has been fixed in in CICS TS 5.4 which is generally available today June 16th 2017.

    For more information see the announcement letter https://www-01.ibm.com/common/ssi/cgi-bin/ssialias?infotype=an&subtype=ca&supplier=897&letternum=ENUS217-113

    Please note the discard of program definitions CEEEV000, CEEEV001, CEEEV002, CEEEV007, CEEEV008, CEEEV009, CEEEV012, CEEEV013, CEEEV014, CEEEV015, CEEEV016, CEEEV017, IBMBPSMA, IBMBPSLA is deliberate and is done by IBM program DFHLEINI immediately prior to PLT phase 2 programs being run. The reason for this is LE region initialisation attempts to load all 18 event handlers which now results in program definitions for all 18 event handlers being autoinstalled, even though the listed programs are not required in a CICS environment. A request to LE to change this behaviour for CICS regions was turned down by the z/OS review board as they did not want such a change made to inservice z/OS releases. The compromise is for CICS to discard the unwanted definitions given that we have had customers in the past query why unwanted event handler definitions are present. This behaviour is documented here https://www.ibm.com/support/knowledgecenter/SSGMCP_5.3.0/com.ibm.cics.ts.installation.doc/topics/dfha1ln.html
