Xss: Can be used to set the java thread stack size. Each thread in the JVM is allocated a stack. The stack size limits the number of threads per JVM. If the stack size it too large, it will result in memory running out as each thread is allocated more memory than required. If the stack space is too small, there will eventually be an exception "Stack Overflow" error. If the stack space is too large, there will eventually be an exception similar to "Unable to create native thread", if the server tries to create more threads.
