Hi,

The main problem is on my processors threading model. I read the doc and it
describes that most processors should be singleton. But in my case my
processor can not be singleton because it depends on some non-thread-safe
complicate calculation libraries.

You can use ThreadLocal to cache the instance of your library per
thread in the processor.

private ThreadLocal<NonThreadSafeExpensiveToCreateUtil> util =
new ThreadLocal<NonThreadSafeExpensiveToCreateUtil>() {
         @Override public NonThreadSafeExpensiveToCreateUtil initialValue() {
             return new NonThreadSafeExpensiveToCreateUtil();
         }
     };

As Camel uses pool of threads, it will keep a single instance of the
util bound to each thread executing the processor.

Cheers.
