Startup fails with "mmap failed for CEN and END part of zip file" on Linux

[trwnh]

With OpenJDK 16:

[trwnh@home paper]$ java -jar paper-1.16.5-778.jar
mmap failed for CEN and END part of zip file
Exception in thread "main" java.lang.IllegalArgumentException

Tried switching to OpenJDK 8 and this happens:

[trwnh@home paper]$ java -jar paper-1.16.5-778.jar
mmap failed for CEN and END part of zip file
Error: An unexpected error occurred while trying to open file paper-1.16.5-778.jar

This looks like either a busted jar or an environment issue, I'd suggest googling that error as it turns up a good number of results

[trwnh]

Hmm, it seems to be FUSE-related? I can run the jar from /mnt/disk3/data/minecraft/paper, but I get the above error at /storage/data/minecraft/paper as stated. /mnt/disk3 is a regular mount, while /storage is a mergerfs mount combining /mnt/disk{1,2,3}

Wondering if there's a proper fix for this or at least a less-inconvenient workaround...

[electronicboy]

the error came from the JVM, not paperclip as such, this is something which would need to be taken to the relevant parties for this

Closing as this is not an issue in paperclip.
