PM41931: Repeatedly changing open mode of module with differing display state using DXL leads to diagnostic logs

IBM Rational DOORS version 9.3.0.4

APAR status

• Closed as program error.

Error description

• Repeatedly changing open mode of module with differing display
  state using DXL leads to diagnostic logs
  
  Steps to reproduce:
  - Create a module with few objects
  - Set the module for sharing
  - Open the module and run the script below:
  -----------------------
  string sPath = fullName(current Module)
  Module mod
  int i = 100
  while (i-- ? 0) {
          print i ', '
          mod = share(sPath, false)
          Object obj
          for obj in mod do break
          if (canLock(obj)) {
                  lock(obj) // (Line 11)
          }
          downgrade(mod)
  }
  -----------------------
  
  DOORS crashes with diagnostic logs.
  
  Work-around:
  Maintain consistency of display state. For example, if while
  using share() perm, display parameter is set to false, even
  while using downgrade(), ensure display parameter is set to
  false
