Unable to connect to EM using Workstation Client.
There is the following message when connecting to the EM using the Workstation Client.
Sometimes a restart of APM allows temporarily reconnecting to the application. Also noticed that it doesn't disconnect an user who is already connected.

Introscope Workstation Release (Build 991408)
Java VM version "Java HotSpot(TM) Client VM 1.8.0_112" from Oracle Corporation


Per Engineering, this seems be a bug, 

However, there is a workaround - Restart the EM and will be able to login through the Workstation client. 


Open a support case to obtain the fix - APM10.7.0HF15_cumulative.zip


Upgrade to CA APM 10.7 SP3  that contains the fix.
