@StephanEwen Yes, I do have at least objects and classes being stored in a
static context. Any easy example (that has also bitten me a few times) is the
class cache that Avro maintains:
https://github.com/apache/avro/blob/master/lang/java/avro/src/main/java/org/apache/avro/specific/SpecificData.java#L146
The Avro API's, unless told otherwise, will use a singleton instance of
SpecificData and will access that shared cache.
Would something like that be enough to cause the classloader to pass
between jobs?
