Claims inclusion check

Question

You can enable / disable assert on ClassLoader .

But how can you determine if they are included?

(I want to use some code paths that perform expensive checks only if the JVM is invoked with statements enabled.)

Answer 1

 boolean assertEnabled = false; try { assert false; } catch (AssertionError e) { assertEnabled = true; } 

Answer 2

 public static boolean areAssertsEnabled() { boolean assertsEnabled = false; assert assertsEnabled = true; // Intentional side effect!!! return assertsEnabled; } 

Answer 3

 ManagementFactory.getRuntimeMXBean().getInputArguments().contains("-ea");
