RAD/RSAD 9.7.03 and higher and EWM Shell share issue - IDE restart fails due to 'Out of Memory' issue

Symptom

1. Re-launch Rational Application Developer version 9.7.0.3 or higher (or Rational Software Architect Designer) when prompted upon the conclusion of the P2 installation of EWM 7.0.1.
2. The IDE may restart after a long period of time. It may not restart at all. A series of core, heap, javacore, and snap dumps will be created in the <installation_home> directory due to an 'Out of Memory' condition.
3. You may receive an error log dialog box that informs you that an error occurred. The dialog box will direct you to a log file that is contained in the <installation_home>\SDP\configuration directory. For example:
