@SevronCarl

Many thanks for the report 👍

We'll try to replicate and resolve.

Have since switched the cards, to a class 10 samsung 32gb just incase the dane-elec is funky.
Installed everything again, but ended up with a similar error.
Due to something with the applicationContext-sonos.xml file,
Java xml errors but I looked into the files it had errors with and there's no invalid xml as the errors reported.

Uninstalled subsonic and java via dietpi-software, then installed 'default-jre' and 'default-jdk' manually.
Reinstalled subsonic, which put java back again too with it in that process, and all seems to be well apart from subsonic_sh.log being full of messages like [GC (Allocation Failure) 10070K->5924K(15872K), 0.0052970 secs] and no media displaying despite media scanning being successful.

But I don't know what process subsonic goes through, if it may still be indexing or building info and will show up later or not.

[SevronCarl]

And now I've restarted it and can't connect to subsonic at all, think I'm gonna put it to bed for a while...
Try something else.

[Fourdee]

Confirmed bug with all systems.

Java issue?
Online doc states Java7: http://www.subsonic.org/pages/installation.jsp#debian
Try with Oracle JRE?

[Fourdee]

Interesting AirSonic is also failing with the same Java errors, looks like a Java specific issue, recent Java update breaking these programs?

Confirmed java 8 gets installed.

@Fourdee
Requirements: Java 7 or later
Should work with java 8, since java 10 is already released...

Will also do some tests here. I would prefer to stay with OpenJDK, if possible...

€: AirSonic install instructions contain installation of OpenJDK-JRE 8 on Stretch: https://airsonic.github.io/docs/install/prerequisites/#on-debian-9

• Check if by default correct $JAVA_HOME is set/used

[MichaIng]

Got it running after manually installing the Buster version of openjdk-8-jre-headless over the Stretch version, even that both share nearly the same version numbers: https://packages.debian.org/de/buster/openjdk-8-jre-headless

On my Stretch VM, after installing AirSonic via dietpi-software, including OpenJDK 8 etc:

systemctl stop airsonic
wget http://ftp.de.debian.org/debian/pool/main/o/openjdk-8/openjdk-8-jre-headless_8u171-b11-1_amd64.deb
dpkg -i openjdk-8-jre-headless_8u171-b11-1_amd64.deb
systemctl start airsonic

Wait for a while until everything is leaded, takes a while, can be watched via htop Java initiates airsonic.war with 100% CPU usage, filling RAM up to around 300M, then CPU usage goes down. Only after this, http://<localIP>:8080/airsonic can be accessed... Puuh Java is crazy overhead, vote against using it for smaller otherwise independent software... 300M RAM, are you sure?? Or is this not normal and might be still case of an issue here?

€: Hah, downgraded again to Stretch OpenJDK and voilà, just need to wait for ~4 minutes again until everything is loaded, and web ui opens up. Perhaps during your tests @SevronCarl @Fourdee you just underestimated the size of Java? On RPi I guess you need to wait much longer than 4 minutes... Also the error messages we face are no real errors, all just warnings and info messages, perhaps stuff that just shows up on first JDK/JRE initiation. I didn't see them after up- and downgrading JRE again.

Also I vote for differentiating between JDK and JRE. SubSonic and AirSonic just need JRE, thus JDK is a huge overhead. Also in both cases consider using the headless packages: https://packages.debian.org/de/stretch/openjdk-8-jre-headless

• Although openjdk-8-jre seems to be needed for gui and web ui software, checking right now if just headless JRE is enough...
  €: Web UI seems to work with just openjdk-8-jre-headless, but I didn't test real music playback etc. Just navigating around a bid. Very slow here, not sure if this is normal?

€€: Okay @Fourdee was already faster about headless JDK/JRE 👍. Hmm, doesn't openjdk-8-jdk-headless depend on openjdk-8-jre-headless depend on ca-certifacates-java, thus just the first need to be installed? https://packages.debian.org/de/buster/openjdk-8-jdk-headless => Just verified on RPi as well... Ah might be different on Raspbian Buster, which I use 😉.

Successfully accessed SubSonic web ui as well with just openjdk-8-jre-headless installed. Seems a bid smaller, just ~200M RAM usage, thus loaded also slightly faster.

@MichaIng

Great work and research 👍

Yep, JRE/JDK we could split, but we'd need to verify/test all software that depends on them. Could take a while.

I'll move this to v6.9, will focus on final testing for v6.8 and release today.

Re-tests:
SubSonic:

• RPi 3 🈯️
• VM 🈯️

AirSonic:

• RPi 3 🈯️ took 3 minutes before web interface was accessable (long init/startup time)
• VM 🈯️

[Fourdee]

Completed. Patched reinstall for v6.9.
