@vicozohili : Could you please share your OpenShift version as well? How can we reproduce this issue? Is it an intermittent issue or is it happening all the time?

[shawkins]

Is this only happening when the client / websocket is closed?

[vicozohili]

finally got back to reviewing this issue and looks like corrupted dependencies cleaning dependency location and allowing IDE to pull them down again seems to have resolved the issue. closing
