--------------------------------------------
Summary: Type check misses
Key: CAMEL-19319
URL: https://issues.apache.org/jira/browse/CAMEL-19319
Project: Camel
Issue Type: Task
Components: came-core
Affects Versions: 4.0-M2
Reporter: Otavio Rodolfo Piske
Assignee: Otavio Rodolfo Piske
Within the core code there are many circumstances where the type checks
performed by our code, causes the JVM to miss a cache hit and enter a slower
code path.
This can be caused when type check (such as an {{instanceof}} check) fails for
a class instance which implements multiple types (incurring in both a cache a
traversal of the secondary supers ArrayList).
The [type-pollution-agent|https://github.com/RedHatPerf/type-pollution-agent]
can be used to identify where this happen. A report is attached to this ticket.
