CXF - SAM monitoring - mixed up message

[Anonymous]

Hi,
we are experiencing a problem when org.apache.cxf.feature.LoggingFeature is applied on cxfEndpoint and large response (30k+) is returned from backend. Response is invalid XML and fails. It seems like response message is being processed by SAM but in the meantime CXF is trying to ship the message further to another processor. If I turn validation off, I see broken message.
Environment:
Talend 5.6.2
Karaf 2.3.9 (supplied with Talend installation)
Apache CXF 2.7.15
Camel-core 2.13.4

Here is simple proxy:

Hi,
Does this issue reproduce on other build version(6.2, 6.3)?
Best regards
