JR60060: Incorrect update logic in set-system-property run-engine command for CRS container

APAR status

• Closed as program error.

Error description

• When using set-system-property run-engine command, the
  jvm.options file will be automatically updated to either create
  the property referenced, or update the existing property with
  the new value referenced.
  
  However, when using this run-engine command for the CRS
  container, it incorrectly uses logic for the property name, so
  that it will update any property which contains the referenced
  property name.
  
  As a result, if you have a scenario where you have following
  properties in jvm.options:
  
  PROPERTY_A=false
  PROPERTY_A_FLAG=false
  
  If you execute the following run-engine command:
  
  run set-system-property PROPERTY_A true
  
  This will incorrectly update the properties as so:
  
  PROPERTY_A=true
  PROPERTY_A_FLAG=true
  

Local fix

Problem summary

• USERS AFFECTED:
   V9 release administrators who use run engine commands to change
   JVM parameters
  
  PROBLEM ABSTRACT:
  Incorrect update logic in set-system-property run-engine command
   for CRS container
  
  BUSINESS IMPACT:
  The property value will be overwritten by a wrong value
  
  RECOMMENDATION:
  

Problem conclusion

• The old run engine commands will set all the parameters which
  containers input jvm parameter name to input jvm parameter
  value. So some similar parameters will be updated to wrong
  value.  The new run engine commands are changed to match the
  input parameter name exactly. They will not overwrite similar
  parameters.
