Trying to run swiftlint through Java subprocess fails (works normally through command line)

Question

I have a java program to run different kinds of linters, calling the linters as a process using ProcessBuilder. So far, other linters have worked for the most part but with swiftlint, i'm facing a strange issue

When I run it normally from the command line, with

swiftlint --enable-all-rules

It works perfectly, but executing the same through my Java subprocess utility

ProcessBuilder processBuilder = new ProcessBuilder("swfitlint", "--enable-all-rules");
Process process = processBuilder.start();

It fails with the following error message

SourceKittenFramework/library_wrapper.swift:31: Fatal error: Loading libsourcekitdInProc.so failed

At first glance it seems like for some reason certain libraries are not available to the java program which are available to when firing a command through bash, but just to be sure, I tried running the following command through my subprocess util

swiftlint --version

swift --version

Both of which worked, meaning Java does have access to swift binaries installed on my machine. Any help would be appreciated.

I'm not still not entirely sure why this happens but i believe it's due to some kind of environment issue on my machine itself. I tried running the same code inside of a docker container that uses the image built from the following base images

FROM openjdk:17-slim as java_base
FROM ghcr.io/realm/swiftlint:latest 
COPY --from=java_base /usr/local/openjdk-17 /usr/local/openjdk-17

and it just worked
