[jira] [Commented] (CAMEL-14267) Conversion fails with NullPointerException when the body is null at the end of a route and an outputType is set
[ https://issues.apache.org/jira/browse/CAMEL-14267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16990607#comment-16990607 ]
Nikhil Vibhav commented on CAMEL-14267:
---------------------------------------
[~ftaysse] I tried this out locally using Camel 2.24.2, but didn't face this issue.
{code:java}
from("timer://foo?repeatCount=1")
.setBody().constant("42")
.to("direct:processFoo");
from("direct:processFoo")
.inputType(String.class)
.outputType(Integer.class)
.process(exchange -> {
System.out.println(exchange.getIn().getBody());
})
.setBody().constant(null)
.process(exchange -> {
System.out.println(exchange.getIn().getBody());
}); {code}
Getting the output as expected and no exceptions are thrown.
{code}42
null
Process finished with exit code 130 (interrupted by signal 2: SIGINT)
{code}
