We are in phase of transferring RA from our old RH6 platform to RH7. After setting up new test environment we are running into error message in all deployments. It is the following:

Dummy has a process error - Could not send files to server <server-name> : Cause: java.lang.Exception: only DEFLATED entries can have EXT descriptor

The error in agent side log is:
2018-11-21 11:44:15,880 [FileHandlers-2] DEBUG (com.nolio.platform.shared.utils.zip.ZipUtils:334) - Unzip folder changed - file [usedActions.dat] size changed
2018-11-21 11:44:15,880 [FileHandlers-2] ERROR (com.nolio.platform.shared.utils.zip.ZipUtils:370) - An Error occurred while trying to extract /opt/ReleaseAutomationAgent/actionslib/export_shared_integrati
ons.zip to /opt/ReleaseAutomationAgent/unzippedActionPacks/export_shared_integrations

For a short period the export_shared_integrations.zip file is downloaded and can be seen on server. That can be unzipped using normal unzip command line utils.
Release Automation 6.4 and higher
Java version: OpenJdk version "1.8.0_191" on NAC and Agent
On the NAC /opt/ReleaseAutomation/actionslib directory contained export_shared_integrations.zip file which I guess was left there due to some previous unsuccessful action.
After removing the file in question i.e. NAC /opt/ReleaseAutomation/actionslib directory contained export_shared_integrations.zip, deployment execution went fine.
