• Handle unchecked exceptions such as UnsupportedOperationException (rather than dying), which may be thrown by filesystems when accessing a Path object discovered as a classpath element. (#553, thanks to @wajda for the report and the helpful info on how to reproduce.)
• Specifically, ignore JrtFileSystem (which throws UnsupportedOperationException if you try to open a new FileChannel on a resource). This filesystem is not needed anyway, as ClassGraph already has the ability to scan all visible modules using the JPMS API.
