Hi Frank and Mike,
It's likely the issue was caused by users who installed 9.6.0.10 (which was a JVM update only) caching classes from Java Toolbox.
9.6.0.11 didn't update the JVM, but did update Java Toolbox. A JVM update clears the cache. Future releases will only update Java Toolbox during a JVM update.
I would suggest attempting a system reboot BEFORE changing the JVM setting. A reboot may also clear the cache. Any user who WASN'T affected by the PCML issue would NOT need to change the JVM setting.
Anyone interested in in joining the 6 week beta program can send me a message in LinkedIN, or contact IBM Support.
Hope this helps!

Hi Frank,
Yes, I figured it out and told Farzi about it so she could let you know. I thought I should put it in the WDSC-L so that more folks might know and be able to take corrective action as needed.
My hypothesis was that there was an bad entry in the shared classes cache in the JVM to changing the setting just turns off using the cache. You can also tinker at clearing the cache or naming it differently and see if the issue comes back. Here is a link to the JVM parm
https://www.ibm.com/docs/en/sdk-java-technology/8?topic=options-xshareclasses
The only down-side of the setting is performance but this is unlikely to affect small-scale interactive usage like RDI but could affect a large WAS server for example.
I don't think that there is anything that the RDI team can directly do about it and without a clear test-case to reliably cause the problem it is unlikely that we could get the Java team to look into it. However historically I have seen this sort of issue fixed by the next Java update, when that will be, I don't know, sorry.
Hopefully this helps a bit with understanding the underlying issue.
As the HelpSystem folks may have said, they recommend all plugin developers to get onboard with the Beta program so you have a preview of what is to come with each release.
All the best, Mike

Hi Mike,
Farzi from the RDi technical support team already pointed me to this.
On all affected systems we know this worked. In case of iSphere and in case of CMOne NG too.
One of the users with this problem has a question. He asked "Do you have any clue what other effect it is going to have, just in case I come across a "difference" later?"
I have a question too.
When I informed Farzi, that this worked he asked me, if he can close the ticket. Is this the permanent solution we have to apply on all affected systems manually in the future or will IBM supply something else?
Frank

Hi Frank,
Edit the eclipse.ini in the RDI install directory and locate the line:
-Xshareclasses:name=IBMSDP_%u
then modify the line to be:
-Xshareclasses:none
and save the eclipse.ini then restart RDI.
Let me know if that fixes the iSphere search issue or not, thanks.

Hi,
if you are using iSphere you shouldn`t update your RDi 9.6 Installation to fix pack 11. On some boxes with RDi 9.6 Fix Pack 11 we get a PCML exception, if we use the iSphere source file search. On most of the boxes with RDi 9.6 Fix Pack 11 everything works fine. At the moment the problem is not reproducable. We have opened a ticket at IBM to find a solution for this problem
Regards
Frank Hildebrandt
