Error description
An entity loaded in ObjectGrid and when try to retrieve the same from ObjectGrid, getting the exception java.io.UTFDataFormatException. This will happen only if the data for the attribute (of type String) is very long. During serialization, this error will be thrown if the length is more than 65535. Exception = com.ibm.websphere.projector.ProjectorException Source = com.ibm.ws.objectgrid.event.ClientGetResponseSystemEvent.writeOb ject probeid = 118 Stack Dump = com.ibm.websphere.projector.ProjectorException: IOException while serializing Tuple com.ibm.ws.projector.ProjectorImpl.serializeTuple(ProjectorImpl. java:936) com.ibm.ws.objectgrid.map.BaseMap$BaseMapObjectTransformer.seria lizeValue(BaseMap.java:4629) Caused by: java.io.IOException: Unable to write tuple attribute 0, type=string at com.ibm.ws.projector.TupleImpl.writeAttributes(TupleImpl.java:88 5) com.ibm.ws.projector.TupleImpl.getBytes(TupleImpl.java:655) com.ibm.ws.projector.ProjectorImpl.serializeTuple(ProjectorImpl. java:934) Caused by: java.io.UTFDataFormatException java.io.ObjectOutputStream$BlockDataOutputStream.writeUTF(Object OutputStream.java:2064) java.io.ObjectOutputStream$BlockDataOutputStream.writeUTF(Object OutputStream.java:1907) java.io.ObjectOutputStream.writeUTF(ObjectOutputStream.java:839) com.ibm.ws.projector.TupleImpl.writeAttributes(TupleImpl.java:82 9)

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere eXtreme Scale who * * use Entity Manager API's and have an * * Entity that has a String attribute that * * exceeds 64K length. * **************************************************************** * PROBLEM DESCRIPTION: A UTFDataFormatException exception * * results when serializing an Entity. * **************************************************************** * RECOMMENDATION: * **************************************************************** The ObjectOutputStream.writeUTF method in the Java API throws a UTFDataFormatException exception if a String attribute is greater than 64K in length.
Problem conclusion
The code has been updated to prevent UTFDataFormatException exceptions from occurring. An interim fix will be provided for the Version 6.1.0.5 release of eXtreme Scale. A future cumulative fix will be provided for releases 7.0 and 7.1. This fix must be applied to both the client and server side of eXtreme Scale. If an interim fix is applied o only one side, an java.io.EOFException exception results.
