Off-Heap native memory leak about nightmonkeys HOT 8 OPEN

I cannot reproduce, i am on a Mac.

from nightmonkeys.

Interesting and slightly concerning.
I managed to build this project on Windows 11

from nightmonkeys.

I ran it with a 1440x960 HEIC file, 135 KB, it ran for over 3000 iterations and i noticed no change on the memory usage.

Is it happening only with the heif plugin, or also with webp/jxl ?

What's you version of libheif ?

from nightmonkeys.

I'll need to figure out the webp read path, I'll do that when I have time.

I managed to build libheif for windows via https://github.com/Microsoft/vcpkg/
Sadly, only libheif 1.14 is available as a Windows port

from nightmonkeys.

I managed to build 1.17.5 from CI to include in my app.

The port file mentions it's on 1.17.6: https://github.com/microsoft/vcpkg/blob/master/ports/libheif/vcpkg.json

from nightmonkeys.

I rebuilt with a fresh pull of the sources.
My libheif on windows is now 1.17.6

java still consumes RAM untill exhaustion with my posted test read loop on Windows.
I'll check out the webp read path soon

java still consumes RAM untill exhaustion with my posted test read loop on Windows.

how many iterations does it take to exhaust the ram ? How much ram does your system have ?

from nightmonkeys.

500 Iters -> java.exe at 1.5GB commit size

1.5k iters -> java.exe at 3.86GB commit size

So, RAM rises pretty fast.
I have 64GB of system memory, which I can exhaust in a few minutes.
Heap Size stays as configured, right now the JVM only "uses" 77MB for the test loop app
