I have a code where I'm passing Autowired configuration class instance to ThreadFactory that is used with ThreadPoolExecutor, and what I saw under load of concurrent calls that some threads are stuck and it seems that there is some deadlock or something in the code at the place were its trying to get some value from the configuration class that was passed. I wanted to know if passing @Autowired classes to threads is safe or how this should be done with Spring.
