a4j:mediaOutput on GF4: "Unauthorized deserialisation attempt" -------------------------------------------------------------- Key: RF-13534 URL: https://issues.jboss.org/browse/RF-13534 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 4.3.5 Environment: Glassfish 4.0, Mac OS X 10.9.1, Java(TM) SE Runtime Environment (build 1.7.0_21-b12), Java HotSpot(TM) 64-Bit Server VM (build 23.21-b01, mixed mode) Reporter: Daniele Benegiamo Labels: glassfish Fix For: 5-Tracking Attachments: MediaOutput.zip On GF4.0 any attempt to use {{<a4j:mediaOutput>}} raises the same exception ("{{java.io.InvalidClassException: Unauthorized deserialisation attempt}}"). Everything works nicely with the old RichFaces 4.1.0. Below you can find a stack trace, a sample page and a sample managed bean as minimum reproducible test case. To keep the test case short, the sample doesn't uses the {{value}} attribute, but exceptions are raised also when using it (e.g. passing a simple {{java.lang.String}}). From a first quick analysis seems that: * basic types (as {{java.lang.String}}) are not properly detected as "de-serializable"; * types implementing {{Serializable}} or {{SerializableResource}} interfaces are impossible to instantiate by {{LookAheadObjectInputStream}} (row 118 - {{Class.forName()}} call in {{isClassValid()}} method - raises a {{ClassNotFoundException}} exception).
