[jira] [Commented] (AMQ-3537) ClassLoadingAwareObjectInputStream
cannot handle deserializing proxies with mixed JDK & non-JDK interfaces
[ https://issues.apache.org/jira/browse/AMQ-3537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13125330#comment-13125330 ]

-----------------------------------
Any chance you can port your unit test to Java, then it could be included in the test suite to validate any future changes. Also in order to include patches or tests in the source you need to ensure that you tick the license grant to apache when you upload your files.

> Project: ActiveMQ
> Issue Type: Bug
> Components: JMS client
> Affects Versions: 5.5.0
> Environment: JDK 1.6.0, RHEL 6.0, ActiveMQ 5.5.0, Tomcat 7, Hibernate 3.6.7.Final, Spring 3.0.3.RELEASE

> When the ActiveMQ client attempts to unpack an ObjectMessage that contains a proxy with a mix of JDK and non-JDK interfaces the ClassLoadingAwareObjectInputStream chooses ONLY the ClassLoader from the first interface in the array of interfaces represented by the proxy. This means that if a proxy's first interface is a JDK class (java.util.List, java.sql.Blob) the core ClassLoader is used. In the event that a non-JDK interface is present in the list of proxied interfaces the same core ClassLoader is used. The Proxy.getProxyClass subsequently throws an IllegalArgumentException because the non-JDK interface class cannot be loaded by the core ClassLoader.
> This problem is extant during deserialization of an ObjectMessage payload that contains a proxy that implements [java.sql.Blob, org.hibernate.engine.jdbc.WrappedBlob, java.io.Serializable] (a blob proxy created by [hibernate SerializableBlobProxy|https://github.com/hibernate/hibernate-core/blob/3.6.7.Final/hibernate-core/src/main/java/org/hibernate/engine/jdbc/SerializableBlobProxy.java]). The impact of this bug is that users of Hibernate cannot use ActiveMQ as a messaging framework if they need to package ValueObjects that have mapped lobs.
