Subject [jira] [Commented] (IGNITE-4211) Update Spring dependency to latest stable version
Date Thu, 13 Apr 2017 11:13:42 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-4211?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15967421#comment-15967421

Vyacheslav Daradur commented on IGNITE-4211:
--------------------------------------------

[~avinogradov]

The most deep point of the error: {{IgniteUtils#forName}}
{{java.lang.ClassNotFoundException: sun.reflect.GeneratedMethodAccessor##}}

It is called by {{OptimizedMarshallerUtils#classDescriptor}} via {{MarshallerContextImpl#getClass}}
{code}
cls = ctx.getClass(typeId, ldr); // couldn't load class for current typeId
// cls is null, but mustn't be null
OptimizedClassDescriptor desc = clsMap.get(cls); // NullPointerException
{code}

As far I know GeneratedMethodAccessor are classes wich generated at runtime by the Java-reflection
to call methods and constructors.

As I understand, one node serialized self-generated reflection class, and other node tryed
to deserialize it.

> It seems the Spring dependency looks outdated for now. Apache Ignite still uses 4.1.0
released two years ago. Could we to update to latest stable version (4.3.4 at the moment)?
