There's something seemingly weird going on when connecting with a browser to the ssl-secured Openwire port of an ActiveMQ (classic) server.
Using this Url: https://AMQ-HOST:OPENWIRE-PORT The browser sends off a GET request and after 30 seconds actually receives a response from ActiveMQ. The payload shows (some non-printable chars removed): ActiveMQ TcpNoDelayEnabled SizePrefixDisabled CacheSize ProviderName ActiveMQ StackTraceEnabled PlatformDetails Java CacheEnabled TightEncodingEnabled MaxFrameSize MaxInactivityDuration MaxInactivityDurationInitalDelay ProviderVersion 5.15.13 Does this behaviour make sense? I would not expect ActiveMQ to reveal this information. On ther server side, the log entry shows: 2020-12-02T18:08:58,684 | WARN | InactivityMonitor Worker | Transport | ivemq.broker.TransportConnection 243 | 79 - org.apache.activemq.activemq-osgi - 5.15.13 | Transport Connection to: tcp://172.22.33.45:4793 failed: org.apache.activemq.transport.InactivityIOException: Channel was inactive (no connection attempt made) for too (>30000) long: tcp://172.22.33.45:4793
