             Summary: Impossible to use custom FileSystemProviders embedded in an application
                 Key: WFLY-6525
                 URL: https://issues.jboss.org/browse/WFLY-6525
             Project: WildFly
          Issue Type: Bug
          Components: Class Loading
    Affects Versions: 10.0.0.Final, 9.0.2.Final
            Reporter: Xavier Dury
            Assignee: David Lloyd


Using a custom {{FileSystemProvider}} inside an application is not possible with Wildfly:

* Using {{Paths.get(uri)}} won't work as {{FileSystemProvider}} caches previously discovered FSPs and won't see those that could be embedded in the application
* Using {{FileSystems.newFileSystem(uri, map, classLoader)}} won't work either because FSPs from {{com.sun.nio.*}} will be discovered and those classes are not visible to the application (and are not exported by sun.jdk module.xml). This will give the following error: {{java.util.ServiceConfigurationError: java.nio.file.spi.FileSystemProvider: Provider com.sun.nio.zipfs.ZipFileSystemProvider not found}}.
