-------------------------------------
Summary: JettyHttpComponent sets selector threads to 0 when
running on 1 CPU
Key: CAMEL-10874
URL: https://issues.apache.org/jira/browse/CAMEL-10874
Project: Camel
Issue Type: Bug
Components: camel-jetty
Affects Versions: 2.18.2, 2.17.5, 2.16.5
Reporter: Nick Houghton
In JettyHttpComponent, "createHttpClientTransport" method the number of
selectors is derived by:
{noformat}
int selectors = Runtime.getRuntime().availableProcessors() / 2;
{noformat}
If the number of available processors is 1, divided by 2, cast to int is 0
which causes an IllegalArgumentException.
The safe way to do this is via Math.max, like the Jetty code does:
{noformat}
int selector = Math.max(1, Runtime.getRuntime().availableProcessors() / 2);
{noformat}
As per the code this is only exercised when maxThreads is not null, otherwise
the default constructor is called and selectors are created properly.
