------------------------------------------

             Summary: java.awt.HeadlessException exception in console proxy on mouse clicks
in XenServer PV VM window
                 Key: CLOUDSTACK-8657
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8657
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: SystemVM
    Affects Versions: 4.5.1
         Environment: Management server: CentOS 6.6 64-bit
Hypervisor: XenServer 6.5
            Reporter: Marina Surkova


Multiple mouse clicks in VM console running on XenServer in PV mode results in console session
disconnect with following text:
"Access is denied for the console session. Please close the window and retry again". 
Problem could not be reproduced for VMs running in HVM mode and does not happen if mouse is
not used for VMs running in PV mode.

Console System VM /var/log/cloud.log seems to indicate root cause of this issue:

Unexpected exception:
