Lucky me, there were libraries available, for mail, JMS, Kafka, logging and so on. Also implementing things in shittier way than Spring is difficult feat to achieve for my modest skillset.

However there were some impossibly complex requirement like thread pool and with great effort I was able to found a solution in standard JDK like :

`ExecutorService exec = Executors.newFixedThreadPool(st.threads);`

Spring could have greatly simplified this code I guess.
