-------------------------------
Summary: On route shutdown timeout
DefaultShutdownStrategy.forceShutdown remains set to true
Key: CAMEL-15245
URL: https://issues.apache.org/jira/browse/CAMEL-15245
Project: Camel
Issue Type: Bug
Affects Versions: 3.4.0
Environment: Linux Ubuntu 5.7.4-050704-generic #202006181331 SMP Thu
Jun 18 13:33:57 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
Reporter: Jh. To.
I see the following behavior with the default shutdown strategy: when the
graceful shutdown of a route times-out, a forced shutdow is executed by Camel.
The following is logged in this case:
{code:bash}
2020-06-25 14:59:57,640 INFO http-nio-127.0.0.1-9080-exec-10 [] []
org.apache.camel.impl.engine.DefaultShutdownStrategy - Starting to graceful
shutdown 1 routes (timeout 10 seconds)
2020-06-25 15:00:07,647 WARN http-nio-127.0.0.1-9080-exec-10 [] []
org.apache.camel.impl.engine.DefaultShutdownStrategy - Timeout occurred during
graceful shutdown. Forcing the routes to be shutdown now. Notice: some
resources may still be running as graceful shutdown did not complete
successfully.
{code}
After the forced shutdown succeeds the following is logged
{code:bash}
2020-06-25 15:00:08,711 INFO http-nio-127.0.0.1-9080-exec-10 [] []
org.apache.camel.impl.engine.DefaultShutdownStrategy - Graceful shutdown of 1
routes completed in 11 seconds
{code}
After the starting the route however the default shutdown strategy from the
camel context has the forceShutdown flag set to true, causing the execution of
the route to fail as follows:
{code:bash}
Caused by: java.util.concurrent.RejectedExecutionException: Run not allowed as
ShutdownStrategy is forcing shutting down, will reject executing exchange:
