PokeMMO Linux Client won't start with java 9

[Viewerisland]

Java 9 has the following issue when trying to launch the game:

 

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/DatatypeConverter

 

Is there anyway around this or do I have to roll back to Java 8

[XelaKebert]

You will likely have to roll back to Java 8 as far as I can tell.

Do you have a full stacktrace? I don't believe we have any remaining usages of DatatypeConverter

 

Edit: It's the updater isn't it?

Yes it's the updater, here is the steps I tried to get the game working.

I use Arch with Java 9, so naturally I didn't think on downloading the .deb or .rpm so I went with the client, when I ran the .sh launch file this was the error:

 

Error: LinkageError occurred while loading main class com.pokeemu.client.Client

       java.lang.ClassFormatError: Illegal field name "if.Object" in class com/pokeemu/client/Client

 

I couldn't get the game to work at all so then I went to try to see if the rpm file would give me any luck, I ran the pokemmo launcher and this was the furtherest I could get:

 

Java options were -Xms64M -Xmx128M

Error: Could not find or load main class com.pokeemu.updater.ClientUpdater

Caused by: java.lang.ClassNotFoundException: com.pokeemu.updater.ClientUpdater

Java options were -Xms128M -Xmx384M

Error: Could not find or load main class com.pokeemu.client.Client

Caused by: java.lang.ClassNotFoundException: com.pokeemu.client.Client

 

Alright then I went on to try my luck with the .deb file and by directly running pokemmo_bootstrapper.jar file this was the issue:

 

java.awt.Label[label0,122,5,69x21,align=left,text=Loading...]

... 4 more

The launcher did launch but it seems like the updater was not working at all. So is there any options to get around using the updater? I would really appreciate it if I can get any help :)

[Desu]

Looks like java9 isn't going to work currently. Will need a bit of work to make it compatible.

[Viewerisland]

Yeah, rolling back to java 8 solved the issue. Is there any plans to make the updater compatible with java 9?

[Desu]

It's on my todo list.

It's really inconvenient to set update-alternatives every time before launch.

Is there a distro where this is already default-jdk or are you installing from an alternate source?

I run this on a 2008 potato running Xubuntu, idk much about Linux yet but can at least verify xubuntu as having the proper java to play. Distro 17.10

 

And on my other newer system I run xubuntu off of a live USB to play (Lol)
