Is this a bug? how to solve it?

When doing a RestAPI "Get" on query capability link for Automation adapter
https://localhost:9443/qm/oslc_auto_test/contexts/_by2W444ACEe6QW4qxSQsw8lw/resources/com.ibm.rqm.execution.ToolAdapter
This  return the list of adapters but it also reset all adapters' heartbeat  timestamp to the time of Doing Get Method
 as a result in adapter console all adapters show green indicator  that all adapter are connect even though no adapter is actually connected to ETM. afterward after a minute or so the indicator chenge to alert and then red square icon and and connection status changed from moment ago to 1 minute a go etc as normal procedure as if adpter disconnected.
interestingly, if I use oslc.where filter it only reset heartbeat of adapters which that filter contains but not all adapter.
I use ETM 7.0.2 ifix 11
Doing Get both in browser & java code behavior is the same

Then How can I get the list of adapters+ related info without this side effect?
Thank you in advance :)
