kryo-users › com.esotericsoftware.kryo.SerializationException: Buffer limit exceeded writing object of type: #199

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. msm + kryo + legacy spring mvc application
2. Override the default max buffer size to 10 
MB(-Dmsm.kryo.buffersize.max=10240000)
3. <Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
            sticky="false"
            memcachedNodes="n1:host1:11211,n2:host2:11211"
            failoverNodes="n1"
            lockingMode="all"
            requestUriIgnorePattern=".*\.(png|gif|jpg|css|js|ico)$"
            sessionBackupAsync="false"
            sessionBackupTimeout="100"
            copyCollectionsForSerialization="true"
            transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory"
    />

What is the expected output? What do you see instead?
Application should work as it did work currently with HttpSession to store 
session info. 
But it's failing due to Buffer limit exceeded writing object of type:

What version of the product are you using? On what operating system?
spymemcached-2.10.2.jar
memcached-session-manager-tc6-1.8.1.jar
memcached-session-manager-1.8.1.jar
reflectasm-1.01.jar
msm-kryo-serializer-1.8.1.jar
minlog-1.2.jar
kryo-serializers-0.11.jar
kryo-1.04.jar
asm-3.3.1.jar

Please provide any additional information below.
We are integrating memcached session manager (msm) + kryo with our legacy 
applications, as part of that testing getting following error. I don't have 
permission to change any code in the legacy applications. So I have to 
transparently migrate an application from HttpSession  to Memcached.

Some useful information, prior to this error I was getting lot of 
ClassNotFoundException, resolved those by placing the jars under 
tomcat6/common/lib. This might not be the good solution, just a work around and 
proceed further I did this workaround. Please suggest if any other solutions to 
overcome this issue.

I'd say you're serializing the whole spring ApplicationContext. Or might there 
be another reason for such big sessions?

The same application + Coherence Web Session+ Kryo and same application + 
Hazelcast Wen Session + Kryo doesn't have this issue. Also we measured the max 
size of the session in those two web sessions framework, max session size is 30 
KB.

msm +  Java Serialization + Spring MVC, going good, but I see one or two issue 
while serializing SPRING SECURITY CONTEXT. Looking into it now. It seems like 
one of our custom authentication class not implemented Serializable, causing 
this issue, let me updated once I'm done with testing.

Cannot serialize session attribute SPRING_SECURITY_CONTEXT for session

Thanks
Yoga

For this one, can you provide a simple spring app that allows to reproduce the 
issue that I could use to debug this?

Hi Martin,

Please find attached  Spring Mvc , where I'm still getting lot below exception, 
when I remove implements Serializable from User class. This is same happening 
in our legacy spring mvc based application. I'm adding Serializable interface 
to classes which are failing one by one, but still the list keep on growing.

Hi Martin,

Any suggestion/direction to avoid the above exception gracefully, because our 
legacy application has tons of classes without Serilizable interface 
implementation.

Thanks
Yoga
