This is what I get:
501 2323 1 0 8:31am ttys001 0:25.08
/Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home/bin/java
[...] -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n [...]
org.apache.catalina.startup.Bootstrap start

Yep, I get it.

Gives me this
java 2323 desilets 5u IPv4 0xad510ad86ad41671 0t0 TCP
*:irdmi (LISTEN)
which seems to indicate that Tomcat is NOT listening on locahost, but on
something called *:irdmi. Not sure that this matters, because from what I can
read on the net, *:irdmi corresponds to port 8000.

Gives me this:
java 2323 desilets 61u IPv6 0xad510ad8630f7d61 0t0 TCP
*:http-alt (LISTEN)
Again, I believe *:http-alt is just an alias for 8080, so it doesn't seem to
matter.
Note that if I start with 'catalina.sh start' (i.e. no jpda), I get *:http-al
for 'lsof -8080' and nothing for 'lsof -8000'.

So far, no. But I appreciate the effort. Any other ideas?

Yep, I get that message when running with jpda
