/**
 * Raised by mockito to emit an error either due to Mockito, or due to the User.
 * All exception classes that inherit from this class will have the stack trace filtered.
 * Filtering removes Mockito internal stack trace elements to provide clean stack traces and improve productivity.
 * <p>
 * The stack trace is filtered from mockito calls if you are using {@link #getStackTrace()}.
 * For debugging purpose though you can still access the full stacktrace using {@link #getUnfilteredStackTrace()}.
 * However note that other calls related to the stackTrace will refer to the filter stacktrace.
 * <p>
 * Advanced users and framework integrators can control stack trace filtering behavior
 * via {@link org.mockito.plugins.StackTraceCleanerProvider} classpath plugin.
