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: 9.0.2.Final, 10.0.0.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}}.
