preference.txt,instance_server.key=0.22815461437707485 instance_server.port=37109is relevant.
If these two lines are deleted, then the next start will workCreated by: rapiz1
Background: I have http and sock proxy set, in the KDE Proxy setting.
and
After readingstrace -f ./processing, I found out that processing try to connect the instance server via the proxy. This didn't work, of course.Seting
proxy.system=falseinpreference.txtsolves the issue.Created by: benfry
Hm, I don't personally know enough about system proxies to understand why enabling it would cause connections to localhost break. Maybe someone else can help.

@rapiz1 can you try it with beta 7?

Working on a fix for this issue. Maybe we should disable proxys when running singleinstance.java?

I now think a sane proxy implementation should handle the loopback address. I haven't tried processing ever since. Maybe this isn't a issue that processing should fix?

Ok, thanks; I can't just ship it out without testing, we'd need someone who's dealing with proxies to weigh in.
As far as I know,
localhostshould not be proxied (why would it be? it's not like the receiving proxy server can redirect traffic back to… 127.0.0.1), but it seems that things have gone back and forth with whether that's the correct behavior in Java or not:https://bugs.openjdk.org/browse/JDK-8025065

https://bugs.openjdk.org/browse/JDK-6737819Java should definitely fix this, I just thought that maybe a temporary solution could be good while the nerds at Oracle work this out.
I also tried building it, no
