Per Engineering, OpenJDK does not contain javaws.jar which needed to launch APM Webstart workstation.

APM does not support IcedTea Java that comes with OpenJDK for webstart. 


Release : 10.7.0

Component : APM Webstart Workstation

OpenJDK 1.8 


Workaround: Install Standalone Workstation client on PC or use Webview / Team center.
