Rich client timeouts

The rich client uses Eclipse menus, commands, and the shortcut menu. Eclipse may evaluate several hundreds or thousands of expressions to control the visibility of any specific command in a menu. In some cases, the Eclipse expression evaluation mechanism may cause problems. To avoid the these issues, Siemens Digital Industries Software recommends adding -Dexpressioncache.enable=Y to the TC_ROOT/portal/portal.bat file. For example: Copy start Teamcenter.exe %* -vm "%JRE_HOME%\bin\javaw.exe" -vmargs -Xmx%VM_XMX% -XX:MaxPermSize=128m -Dexpressioncache.enable=Y -Xbootclasspath/a:"%JRE_HOME%\lib\plugin.jar"; "%JRE_HOME%\lib\deploy.jar";"%JRE_HOME%\lib\javaws.jar" %DJIPJL_VMARG%
