-----------------------------------
Summary: RPC proxy classloading should use Flink class' classloader
Key: FLINK-4403
URL: https://issues.apache.org/jira/browse/FLINK-4403
Project: Flink
Issue Type: Sub-task
Components: Distributed Coordination
Environment: FLIP-6 feature branch
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.2.0
The RPC service's proxies use the {{ClassLoader.getSystemClassLoader()}} for
all reflective classloading.
In settings where Flink runs embedded, the Flink framework classes may not be
in the System classloader, but for example in the classloader of an OSGI
bundle. It is hence better to use the classloader of a Flink Framework class.
In most cases, that will be the system classloader, in other cases it will be
the classloader for the Flink code bundle:
{{RpcService.class.getClassLoader()}}.
