Out of memory despite 1G heap space assigned

## Problem description

*Describe your problem here. Describe what you want to happen, and what happens
if you try to do it. If you have a stack trace or any logs, please format them using
github's triple-backquote notation, or if they are large you may also consider
attaching them as a file or gist.*

My playlists are stored as m3u files in the Media file tree, and they contain relative paths.
I wondered why they didn't show up in Airsonic (advanced), and checked the log.

Amongst others, I discovered an out-of-memory error related to playlist scanning.
Unfortunately, the error message doesn't tell the problematic file.
And even more unfortunate, the scan seems to stop after this error!

Hence, I'd like to report 3 issues here:
1. Please enhance the error message shown below to print the file name.
2. 1G of heap space should be enough to scan a library of 62,000 music files and a handful of playlists.
3. If running out of memory when scanning a file, skip it and continue with the next on.

This is my docker-compose.yml:
```
root@server:/mnt/data/var/airsonic# cat docker-compose.yml
version: "3"

```

And this is the error I get:
