java.lang.NoClassDefFoundError

[Christian Schlichtherle]

Hi,

Alan, how could the default file system provider get replaced? AFAIK from reading the source code of the java.nio.file package, it’s hard coded. 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.

Lars, I suppose something must be unique to your environment. 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?

Regards,
Christian Schlichtherle

It is possible that TrueZip is hitting a recursive initialization issue? The stack trace doesn't tell all so it's not clear what is triggering de.schlichtherle.truezip.fs.archive.tar.TarDriverService to load. Christian might be able to provide a bit more background as to how it initializes.
