Claus Ibsen commented on CAMEL-20199:
-------------------------------------

Make it possible to enable virtual threads without having to set a -D JVM 
system property.

So you can do in camel-jbang / camel-spring-boot etc.

camel.main.virtualThreadsEnabled = true

This requires possible to read this application.properties value eager 
specially to detect this option so the thread pools can be in virtual mode 
eager.

There is code in camel-main we use for boostrap camel for all the runtimes, 
that is a good place to hook this code into

> For full support of Virtual Threads, several sub-tasks need to be done:
>  * Avoid Lengthy and Frequent Pinning by replacing synchronized blocks with 
> ReentrantLocks (use the option {{-Djdk.tracePinnedThreads=full}} to print 
> stack traces when a thread blocks while pinned)
>  * Don't Cache Expensive Reusable Objects in Thread-Local Variables by 
> avoiding thread locals when possible since when using Virtual Threads, the 
> objects will never be reused so if the thread-local variables are never 
> reset, it will end up with an OOME.
>  * Use Semaphores to Limit Concurrency instead of relying on the size of the 
> thread pool when applicable
>  * Allow to expose {{ThreadPerTaskExecutor}} through JMX indeed so far it is 
> limited to {{ThreadPoolExecutor}}
