The root cause exception says the JVM can’t initialize java.nio.file.FileSystems$DefaultFileSystemHolder. I can spot no recursion in the entire stack trace.

Maven Central statistics tell me there are more than thousand downloads of TrueZIP components from unique IPs every month, but I have not heard of this problem before nor am I able to reproduce it. Maybe the JDK installation just got corrupted and a simple reinstall would fix it?

If TrueZip doesn't support that then ignore my comment as I can't think of any other reason why the built-in implementation could not initialize.

Sorry, I forgot about this detail. However, the root cause exception specifically mentions java.nio.file.FileSystems$DefaultFileSystemHolder, so I suppose the system property hasn’t changed (and no, TrueZIP neither uses nor changes this system property).
