Hi,

I've got an error while JBoss EAP 6.1 is trying to de-serialize my session attribute:

While spending more time on investigating this issue I've found that the problem is around de-serializing empty array property. Let's say my session attribute is a an object of class ValueWrapper(serializable class) and it has a map property with value object which is empty array, like "new Person[] {}" (where Person is serializable). And JBoss is throwing those exception above while de-serializing such empty array object. I definitely know that the problem is with empty array since replacing it to empty list is resolving the issue.

Is it a known issue and any workaround available other than refactoring my code and replacing arrays to lists?

Plus I think there is one more issue here:

"Caused by: java.lang.ClassCastException: org.test.ValueWrapper cannot be cast to java.lang.String

  at org.jboss.marshalling.ModularClassResolver.resolveClass(ModularClassResolver.java:103)"

Looks like original problem was swallowed somewhere and marshalling code is trying to cast my object to String at ModularClassResolver.java:103

I haven't seen this one before. Have you tried against the WildFly latest community version to see if it is fixed there? Or maybe try a later version of EAP?

[yakimovich]

Nope, I didn't try WildFly or latest version of EAP since we are using 6.1 version only.

The only thing I tried is to upgrade WELD version from 1.1.13 to 1.1.23 and it didn't help

[jaikiran]

Dzmitry, dmlloyd just fixed this here https://developer.jboss.org/message/909131#909131

Hi Jaikiran Pai,

Are you aware in which version of EAP this fix was released.

We are using 6.2 and can still see this error.
