--------------------------------
Summary: Janino's classloader has an unexpected behavior when its
parent classloader throws an ClassNotFoundException with a cause set
Key: SPARK-15622
URL: https://issues.apache.org/jira/browse/SPARK-15622
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Yin Huai
Assignee: Yin Huai
Priority: Critical
At
https://github.com/aunkrig/janino/blob/janino_2.7.8/janino/src/org/codehaus/janino/ClassLoaderIClassLoader.java#L80-L85,
Janino's classloader throws the exception when its parent throws a
ClassNotFoundException with a cause set. However, it does not throw the
exception when there is no cause set. Seems we need to create a special
ClassLoader to wrap the actual parent classloader set to Janino handle this
behavior.
