Java™ SE Development Kit 8, Update 102 Release Notes
Jul 19, 2016 · When a large TLS (Thread local storage) size is set for Threads, the JVM results in a stack overflow exception. The reason for this behavior is that the reaper thread was created with a low stack size of 32768k. When a large TLS size is set, it steals space from the threads stack, which eventually results in a stack overflow.

Configuring Stack Sizes in the JVM | Baeldung
Jul 07, 2020 · To change the stack size, we can use the -Xss tuning flag. For example, the -Xss1048576 sets the stack size equal to 1 MB: java -Xss1048576 // omitted. If we don't want to calculate the size in bytes, we can use some handy shortcuts to specify different units — the letter k or K to indicate KB, m or M to indicate MB, and g or G to indicate GB. . For example, let's see a couple of different

Some applications require stacks that are larger than the default size; for example, a graphics-intensive Java program can require a larger stack, which may require an increase …

When to use primitive vs class in Java? - Software
In Item 5, of Effective Java, Joshua Bloch says. The lesson is clear: prefer primitives to boxed primitives, and watch out for unintentional autoboxing.
