I love the premise of disrupting the conventional narrative and was reminded of that constantly when debating some of the more controversial features and problems in Java. It’s a feature, not a bug… One of my favourite things about Java is its tendency to move slowly and deliberately. It doesn’t give us what we want right away.

Garbage Collection (GC) plays an important role in Java’s memory management. It helps to reclaim memory that is no longer in use. A garbage collector uses its own set of threads to reclaim memory. These threads are called GC threads. Sometimes JVM can end up either with too many or too few GC threads.
