Subject: Re: Fw: locating blocked port
I finally managed to get jabref to run.
I looked at waht aprocess was using the PIS as you suggest.
$ ps -fp 1675
UID PID PPID C STIME TTY TIME CMD
haines 1675 1559 0 Feb01 tty1 00:04:36 java -jar
/usr/local/share/JabRef/JabRef-3.2.jar
I thn kill the process and verify that port 6050 is not being used.
I then try to start by old version (3.2) of jabref:
$ java -jar /usr/local/share/JabRef/JabRef-3.2.jar &
[1] 1867

It seems javref is trying to load two databases but it but it does
not display. I suspect that is because my jabef is too old.
Neverthesless java owns port 6050 and so I kill the process. I next
load the up to date version of jabref
$ jabref

There seem to be problems
with OpenJDK and the default GTK Look&Feel. Using Metal L&F
instead. Change to another
L&F with caution.

This this time jabref started. I opened three databaes it didn't open
automatically. Another database it did see. I pyt thst issue aside.
While writing this message jabref crashed and no longer claims
port 6060. I restarted it and so far it has no crashed.
