---------------------------------
Assignee: Jens Deppe
> PdxInstance.getObject() is using class from older jar in case of Reconnect

> Key: GEODE-6559
> URL: https://issues.apache.org/jira/browse/GEODE-6559
> Project: Geode
> Issue Type: Bug
> Components: configuration, management, serialization
> Reporter: Jens Deppe
> Assignee: Jens Deppe
> Priority: Major
>
> Given a function as below:
> {code:java}
> public void execute(FunctionContext context) {
> RegionFunctionContext rctx = (RegionFunctionContext)context;
> Region<Object, Object> dataSet = rctx.getDataSet();
> Object o = ((PdxInstance)context.getArguments()).getObject();
> LogService.getLogger().warn(o.getClass() + " loaded from " +
> getClassLoaderJar(o.getClass()));
> printCallerStack("Function execution called from");
> LogService.getLogger().warn("Thread context classloader is " +
> Thread.currentThread().getContextClassLoader());
> LogService.getLogger().error(this);
> LogService.getLogger().warn(Student.class + " loaded from " +
> getClassLoaderJar(Student.class));
> LogService.getLogger().warn(o.getClass() + " args class parent is " +
> o.getClass().getClassLoader().getParent());
> LogService.getLogger().warn(o.getClass() + " loaded from " +
> getClassLoaderJar(o.getClass()));
> LogService.getLogger().warn(this.getClass() + " loaded from " +
> getClassLoaderJar(this.getClass()));
> Student args = (Student) o;
> LogService.getLogger().warn("args = " + args);
> Integer first = 1;
> Integer second = 2;
> LogService.getLogger().info("Function returning result " +
> this.getClass() + " loaded from " + this.getClass().getClassLoader());
> rctx.getResultSender().lastResult(first * second);
> }
> {code}
> It works fine in case of normal operations and jar --deploy , but in case of
> auto-reconnect, the below line
> {code}
> Object o = ((PdxInstance)context.getArguments()).getObject();
> {code}
> Loads the class from older jar
> {code}
