Cannot get bytes from InputStream for DEPLOYMENT_ROOT VirtualFile.openStream() on second call --------------------------------------------------------------------------------------------- Key: WFLY-783 URL: https://issues.jboss.org/browse/WFLY-783 Project: WildFly Issue Type: Bug Components: OSGi, Server Reporter: Thomas Diesler The effect is that the copy of a installed OSGi bundle is 0bytes in the data/osgi-store area Digging into this shows that during the first call isDirectory() is false and the file gets mounted. The returned stream works fine. For the second call isDirectory() is true and e read() on the returned InputStream returns -1 {code} public InputStream openStream() throws IOException { if(isDirectory()) { return new VirtualJarInputStream(this); } final VFS.Mount mount = VFS.getMount(this); return mount.getFileSystem().openInputStream(mount.getMountPoint(), this); } {code} I assume that the root VirtualFile {code} VirtualFile virtualFile = deploymentUnit.getAttachment(Attachments.DEPLOYMENT_ROOT).getRoot(); {code} should be readable twice.
