JProfiler with Docker

DockerFile should have JProfiler installation.

RUN wget <JProfiler file location> -P /tmp/ && \
  tar -xzf /tmp/<JProfiler file> -C /usr/local && \
  rm /tmp/<JProfiler file>

Thread pools on the JVM should usually be divided into the following three categories:

Each of these categories has a different optimal configuration and usage pattern.

	val rejectionHandler = RejectionHandler.default
	def logDuration(inner: Route): Route = { ctx =>
	val start = System.currentTimeMillis()
	// handling rejections here so that we get proper status codes
	val innerRejectionsHandled = handleRejections(rejectionHandler)(inner)
	mapResponse { resp =>
	val d = System.currentTimeMillis() - start
	logger.info(s"[${resp.status.intValue()}] ${ctx.request.method.name} ${ctx.request.uri} took: ${d}ms")
	resp
	}(innerRejectionsHandled)(ctx)

	// This is a class that attempts to stop you accessing variables outside a lock.
	//
	// It does not do a perfect job, but can catch some common kinds of mistake, in
	// particular when you accidentally try to work with objects inside closures that
	// end up running later, outside the locked region (or in a different thread).

	// EXAMPLE

	val bank = ThreadBox(object {
	val accounts by arrayListOf(10, 0, 0, 0).guard()

	# E.g. TaskClass = CaseClass('name', 'owner', 'pid')
	# task1 = TaskClass(name = "hello", owner = "brian", pid = 15)
	# task2 = TaskClass(name = "world", owner = "brian", pid = 13)
	# tasks = [task1, task2]
	#
	# filter(lambda task: task.where(owner = "brian"), tasks) => [task1, task2]
	# filter(lambda task: task.where(owner = "brian", pid = 13), tasks) => [task2]
	#
	# matcher = TaskClass(pid = 13)
	# filter(lambda task: task.match(matcher), tasks) => [task2]
