Internal Server Error (500) when using directory-listing in FileHandler ----------------------------------------------------------------------- Key: WFLY-11722 URL: https://issues.jboss.org/browse/WFLY-11722 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 15.0.1.Final Reporter: Adam Krajcik Assignee: Flavia Rainone Priority: Minor When I added a bad symlink to the *welcome-content* and allowed *directory-listing* in the file handler of the *welcome-content* server returns Internal Server Error (500) when accessing the folder containing the bad symlink. However, no exception is logged in the output on WildFly. I also tried to use simple example application - _File Serving_ from [Undertow Examples|https://github.com/undertow-io/undertow/tree/master/examples] where I can see the following exception when accessing the directory with the bad symlink: {code} java.lang.RuntimeException: java.nio.file.NoSuchFileException: /home/akrajcik/Pictures/pictures at io.undertow.server.handlers.resource.PathResource.getLastModified(PathResource.java:62) at io.undertow.server.handlers.resource.DirectoryUtils.renderDirectoryListing(DirectoryUtils.java:139) at io.undertow.server.handlers.resource.DirectoryUtils.renderDirectoryListing(DirectoryUtils.java:162) at io.undertow.server.handlers.resource.ResourceHandler$1.handleRequest(ResourceHandler.java:233) at io.undertow.server.Connectors.executeRootHandler(Connectors.java:364) at io.undertow.server.HttpServerExchange$1.run(HttpServerExchange.java:830) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1160) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.lang.Thread.run(Thread.java:811) Caused by: java.nio.file.NoSuchFileException: /home/akrajcik/Pictures/pictures at sun.nio.fs.UnixException.translateToIOException(UnixException.java:98) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:114) at sun.nio.fs.UnixException.rethrowAsIOException(UnixException.java:119) at sun.nio.fs.UnixFileAttributeViews$Basic.readAttributes(UnixFileAttributeViews.java:67) at sun.nio.fs.UnixFileSystemProvider.readAttributes(UnixFileSystemProvider.java:156) at sun.nio.fs.LinuxFileSystemProvider.readAttributes(LinuxFileSystemProvider.java:111) at java.nio.file.Files.readAttributes(Files.java:1748) at java.nio.file.Files.getLastModifiedTime(Files.java:2277) at io.undertow.server.handlers.resource.PathResource.getLastModified(PathResource.java:60) ... 8 more {code}
