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

Troubleshooting


Problem

After a successful P2 installation of IBM Engineering Workflow Management (EWM) version 7.0.1 client, attempts to restart to the Rational Application Developer version 9.7.0.3 and higher IDE and the Rational Software Architect Designer version 9.7.0.3 and higher fail due to an 'Out of Memory' condition.

Symptom

As an example, following the P2 installation of the IBM Engineering Workflow Management 7.0.1 client, a restart of Rational Application Developer fails. 
To reproduce the issue:
  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:

Cause

There is a memory leak in the Eclipse OSGI Felix.Resolver that is causing this problem. For more information, see the Eclipse bug.

Diagnosing The Problem

  1. Run Rational Application Developer version 9.7.0.3 or higher (or Rational Software Architect Designer 9.7.0.3 or higher).
  2. Perform a P2 installation of the IBM Engineering Workflow Management 7.0.1 client.
  3. Restart the IDE at the conclusion of the installation. 
  4. Check the installation directory for core, heap, javacore, and snap dumps. 

Resolving The Problem

To resolve the issue, modify the eclipse.ini file java maximum heap size argument (-Xmx) by increasing the value from 3gb to 4gb. Save the change and attempt to restart the IDE again. 
For example:"-Xmx3072m" must be changed to "-Xmx4096m" or "-Xmx4G"
This change is only required for the initial restart of the IDE. After the IDE has been started one time, the eclipse.ini value can be restored to its original value. 
Alternatively, open a terminal, navigate to the <installation_home> installation directory and launch the IDE using the -initialize argument. For example:
eclipse.exe -product com.ibm.rational.rad.product.v97.ide -initialize
