NPE while invoking tinylog from an AIDL remote interface callback

My code is throwing an exception for this constructor:

	public ServiceLoader(final Class<? extends T> service, final Class<?>... argumentTypes) {
		this.service = service;
		this.argumentTypes = argumentTypes;
		this.classLoader = Thread.currentThread().getContextClassLoader();
		this.classes = loadClasses(classLoader, service);
	}

I believe Thread.currentThread().getContextClassLoader(); is returning null in certain instances in my app. I don’t understand enough about Java or AIDLs to see what’s happening here, but suffice it to say calls to log functions (such as Logger.trace()) are crashing when they are invoked from very specific interface call backs in my app which use AIDL and are on a background thread. Running Logger.trace on the main thread from within the interface callback fixes the issue, but I am worried now there could be places in my code I don’t make this fix, and also that I might be introducing other subtle issues I don’t know about, like this one.

This is probably an Android only problem, but would love to know what the cause is and how I might mitigate it. It’s super difficult for me to try and make a reproducible sample because I am seeing the error in an SDK dependency which uses TinyLog

I’ve tried it with a super simple AIDL / Service sample and can’t repro. So it must be something relatively specific. I will try and create a very simple project with nothing but the Service I am using. Versions are:

  api 'org.tinylog:tinylog-api-kotlin:2.0.1'
  api 'org.tinylog:tinylog-impl:2.0.1'
