Has the Java dependency moved on from 8 to 11? :-(

PS I'm trying to get this running on a DSM 6.2.4-25556 Update 6 , Synology DS212j with the ARM (Marvell Kirkwood 88F6281) so am limited to JAVA SE Embedded.

So can't update beyond ejdk-8u211-linux-arm-sflt.tar.gz

Doh..
https://github.com/bwssytems/ha-bridge/releases/tag/v5.4.1

both these are J11...

• ha-bridge-5.4.1-java11.jar
• ha-bridge-v5.4.1.jar

ha-bridge-5.4.1.jar is the java 8 version!

I'd incorrectly assumed from the datestamp that the v5.4.1.jar was the one to plump for!
