Hi,
When I try to retrieve a stored variableInstance (variable for a
processInstance or a taskInstance) whose type is ByteArrayInstance
(Serializable object for example), the object can not be deserialized. It seems
that the byte array retrieved from database is truncated.
Here is the stack trace.
java.lang.RuntimeException: couldn't deserialize object
