Release : 10.7.0

Component : APM Webstart Workstation

OpenJDK 1.8 


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. 


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