-------------------------------------
Summary: Illegal parameter type: OnWindowExpirationContextParameter
Key: BEAM-12578
URL: https://issues.apache.org/jira/browse/BEAM-12578
Project: Beam
Issue Type: Bug
Components: beam-model
Affects Versions: 2.29.0
Reporter: Stefan Wachter
{{OnWindowsExpirationContext}} can not be used as a parameter for {{DoFn}}
methods annotated by {{@OnWindowExpiration}}. The following exception is raised:
{code:java}
java.lang.IllegalArgumentException:
org.opennms.nephron.cortex.PaneAccumulator$PaneCombinerFn: Illegal parameter
type: OnWindowExpirationContextParameter{}{code}
As a workaround a parameter of type {{OutputReceiver}} can be used, though.
