Hi all,
I was going through the Resequencer camel component available in the
link: http://camel.apache.org/resequencer.html
On trying the resequencer camel component with the StreamResequencer
config with the code below:
from("jms:queue:nq1").
convertBodyTo(String.class).
resequencer(constant("1000")).stream(new
StreamResequencerConfig()).
convertBodyTo(String.class).
to("jms:queue:nq2")
I am getting the below Exception in the Console:
java.lang.ClassCastException: java.lang.String

SEVERE: java.lang.String
Is there any problem with the above code or Is it the bug in the
Resequencer Camel component?
Thanks and Regards,
