I have no problems running that under Zulu 11.

okay… good to know… will have a look what causes my systeminfo items to stop.

Now i tried ist again in a Debian VM on my synology. Used the master Branch and tried to switch ti Zulu 11 32 Bit. Got the following errors:

Error are made with the debug option on

Hmmm., What distro are you on i.e. what does cat /etc/os-release return. I think it might not have all of the preinstalled packages, did you run the unattended setup before trying to install Zulu11? I believe it is because zlib is not installed on your system.

Result of the cat command is

PRETTY_NAME="Debian GNU/Linux 10 (buster)"
NAME="Debian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

and as far as i know the zlib is part of the zliblg and this package is upto date

zlib1g ist schon die neueste Version (1:1.2.11.dfsg-1).

At the end it is a plain debian where i installed openhabian with wget an made the steps i reuire.

Your wrote that you tried to switch to Zulu 11 32 Bit
and that Zlib is installed

is it the 32bit or 64bit library ?

In case you use java based on 32bit you also need to install related 32bit libraries.

I tried Zulu 11 64 Bit als well and it did not work

same or an other error message ?

Sorry, but did not looked at the error, because i had not the time to check that carefully. After teh first error it was my goal to bring openHAB online again

i had some hope to solve the iCalendar handshake by newer java.

@mstormi will be there any new version of the tr064 binding?

Running oh on rpi 3B+ openhabianpi (still stretch) and switched to java 11 some days ago. No complaints up to know …

This is the one i’m using

now i fixed my instllation error and found that rules with jython are not working. They are simply not loaded

Sorry to repeat myself, but you will need to wait until my PR is merged or I update the beta Jython addon…

Did you realize this “maybe openhabian-config issue” deleting certs when switching to java11, @mstormi ?

Dlinksmarthome binding doesn’t work due to a problem with javax/xml/soap/SOAPException not being found.

Java 11/32 works for me again after updating openhabian-config itself. Be shure to select “master”.
