[jetty-users] alpn on Ubuntu

[Bill Ross <ross@xxxxxxxxxxxx>]

I'm trying to go from 9.3.3 to 9.4.1, drop-in works fine on MacOS, but 
on Ubuntu with the same Java version it can't get over alpn:

java.lang.IllegalStateException: Unable to register module:

$ java -version

Exists: 
/ops/jetty-distribution-9.4.1.v20170120/modules/alpn-impl/alpn-1.8.0_60.mod

My run script:

#JETTY_HOME=/ops/jetty-distribution-9.4.1.v20170120
JETTY_HOME=/ops/jetty-distribution-9.3.3.v20150827

java -Xmx3048M \
    -jar $JETTY_HOME/start.jar \
    jetty.home=$JETTY_HOME \
    jetty.base=/ops/jetty-base

I don't see anything apropos in the archives. I did some sleuthing on 
the same issue trying to go to 9.3.9, but got no response:

http://jetty.4.x6.nabble.com/Jetty-Release-9-3-9-v20160517-td4965602.html#a4965607

By the way, I'm not using https in case not needing security somehow 
will allow me to sidestep the issue.

Perhaps it's worth filing a bug on an unhelpful exception?

Thanks,

Bill
