dumpThreads

public static java.lang.String dumpThreads()

Dumps stack traces for all the threads if the JVM supports it. The result is returned as a string, ready to print. If the JVM doesn't have the method Thread.getAllStackTraces i.e, we are on a JVM < 1.5, or if we don't have the permissions: java.lang.RuntimePermission "getStackTrace" and "modifyThreadGroup", a message saying so is returned instead.

Returns:

stack traces for all live threads as a string or an error message.

isDeferredConstraintViolation
