Hi,

This error in itself means that the required java plugins needed to run the operations could not be deployed to the worker. This can happen due to various reasons such as:

- certificate validation issue between worker and central 

-disk space issues

- conflicts with existing plugins

While you could check for some of these yourself, opening a support ticket would help to fix it and help you have steps to identify and fix this type of issue in the future.

Hope this helps,

Vlad

VladM : Thanks a lot for your reply.

Finally we resolved the issue by pointing OO to a newer java version (since it is a very old OO version which used Java 7).

We have installed java 8 (Which conatins the tools jar file)  and after pointing OO to the JDK directory the problem disappeared.

Thanks a lot

OO is installed along with a JRE with which it was tested and certified to work. Since this JRE is usually the opensource java not the oracle one, replacing it with the equivalent oracle java is supported, however upgrading to a newer version of java comes with potential errors which cannot be accounted for and any failures resulting from such will not be subject to support.

In case there is a need to upgrade java upgrading to a newer version of OO which comes with a newer java version is the only correct answer.
