ConcurrentHashMap deserialization fails with JDK 7 -------------------------------------------------- Key: JBSER-131 URL: https://issues.jboss.org/browse/JBSER-131 Project: JBoss Serialization Issue Type: Bug Affects Versions: 1.1.0 Beta Environment: jdk1.7.0_21 and jdk1.7.0_25 64-bit Reporter: Constantine Nosovsky Assignee: Clebert Suconic java.util.concurrent.ConcurrentHashMap deserialization fails with java 7 runtime with the following error: Caused by: java.lang.RuntimeException: Unexpected datatype 28 at org.jboss.serial.objectmetamodel.FieldsContainer.readField(FieldsContainer.java:181) at org.jboss.serial.objectmetamodel.FieldsContainer.readMyself(FieldsContainer.java:218) at org.jboss.serial.persister.ObjectInputStreamProxy.readFields(ObjectInputStreamProxy.java:224) at java.util.concurrent.ConcurrentHashMap.readObject(ConcurrentHashMap.java:1540) Here is the unit test to reproduce the issue (just added to the ReadObjectTestCase) {code} public void testCHMapOnJBossSerialization() throws Exception { ConcurrentHashMap<Object, Object> chm = new ConcurrentHashMap<Object, Object>(); ByteArrayOutputStream bout = new ByteArrayOutputStream(); JBossObjectOutputStream objout = new JBossObjectOutputStream(bout); objout.writeObject(chm); objout.flush(); ByteArrayInputStream bin = new ByteArrayInputStream(bout.toByteArray()); JBossObjectInputStream objinput = new JBossObjectInputStream(bin); ConcurrentHashMap<Object, Object> newObject = (ConcurrentHashMap<Object, Object>)objinput.readObject(); assertTrue(chm.equals(newObject)); } {code} Originally occurred with 1.0.3 version, but the latest trunk revision (448) has the same issue.
