OpenJDK Memory Leak

[r0ck4ev3r]

When I launch any haven(modded or not) thru steam the OpenJDK will eat ram till it crashes;
With original Java .jar no issues.

Is anyone else seeing this issue launching through steam's portal?

From Hurricane client's Discord server (info channel):

I've also been playing on GraalVM 21 (some different open-source java distribution based on OpenJDK), and I seem to get like 15-20 extra FPS out of the client.

https://www.graalvm.org/downloads/ (select 21 from the drop-down menu).

Personally I have Java 15 and Hurricane (standalone.) The Steam version of Hurricane should use an on-board version of Java.

Steam Note: The Steam Workshop client is already using Java 23 (not working with the standalone client for now), so you don't have to change your Java version if you're playing through Steam via the Workshop client.

So the temp fix I ended up using is to: force steam to stop using OpenJDK

I used Java 25.0.1, and moved its Java, Javaw, and Javac executables into steams' \common\Haven\jre

I had the same issue and it turns out it was connected to discord detecting game, when I toggled that off in discord the issue went away.

I don't think it's an issue intrinsic to OpenJDK, at least. I also use OpenJDK, and I haven't had any detectable memory leaks.

That's interesting if true. Can anyone else confirm?

I also recorded now the behaviour. I don't even need to get into the world. This is recorded with freshly downloaded autohaven, but client from steam is showing the same behaviour.

The memory usage will climb endlessly, and performance of the game will deteriorate until it is unable to pump next frame at all

I am having the same exact issue...

So it helps if you turn off Discord's game detection?

Ok, so potential fix.

When I stream the game play in Discord the memory leak speed is reduced by about 10 times.
I can actually play the game at full frames and it takes around 5 minutes before my ram is maxed out.

I have tested multiple times, literally streaming the game while it runs stops 90% of the way.

I, on the other hand, have to kill the Discord process every time, otherwise I encounter a memory leak.
