Bug ID: 61448
Summary: Cluster StaticMember (McastService:Required property
"tcpListenPort" is missing)
Product: Tomcat 7
Version: 7.0.70
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Cluster
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Hello,
Cluster static members seem to fail since version 7.0.70 (also
reproduced in 8.0.45, and is the same code than tomcat 9):
SEVERE: The required Server component failed to start so Tomcat is
unable to start.
...
Caused by: org.apache.catalina.tribes.ChannelException:
java.lang.IllegalArgumentException: McastService:Required property
"tcpListenPort" is missing.; No faulty members identified.

It seems to me that it's always necessary to initialize
membershipService, maybe something like that (untested):
