  - ### addClassTest

    public static void addClassTest​(Closure test)
    Adds a groovy.lang.Closure to test whether the stack trace element should be added or not.

    The groovy.lang.Closure will be given the class name as parameter. the return value decides if the element will be added or not.

    - true - trace element will be added to the trace
    - false - trace element will not be added to the trace
    - null - continue with next test
    Groovy truth will be used to determine true and false, null is excluded from defaulting to false here. If all tests have been executed and all of them skipped, then the groovy standard filtering will take place.
    Parameters:
      `test` - the testing groovy.lang.Closure

  - ### sanitize

    public static Throwable sanitize​(Throwable t)
    Remove all apparently groovy-internal trace entries from the exception instance

    This modifies the original instance and returns it, it does not clone

    Parameters:
      `t` - the Throwable whose stack trace we want to sanitize
    Returns:
      The original Throwable but with a sanitized stack trace

  - ### printSanitizedStackTrace

    public static void printSanitizedStackTrace​(Throwable t, PrintWriter p)

  - ### printSanitizedStackTrace

    public static void printSanitizedStackTrace​(Throwable t)

  - ### isApplicationClass

    public static boolean isApplicationClass​(String className)

  - ### extractRootCause

    public static Throwable extractRootCause​(Throwable t)
    Extracts the root cause of the exception, no matter how nested it is
    Parameters:
      `t` - a Throwable
    Returns:
      The deepest cause of the exception that can be found

  - ### sanitizeRootCause

    public static Throwable sanitizeRootCause​(Throwable t)
    Get the root cause of an exception and sanitize it for display to the user

    This will MODIFY the stacktrace of the root cause exception object and return it

    Parameters:
      `t` - a throwable
    Returns:
      The root cause exception instance, with its stace trace modified to filter out groovy runtime classes

  - ### deepSanitize

    public static Throwable deepSanitize​(Throwable t)
    Sanitize the exception and ALL nested causes

    This will MODIFY the stacktrace of the exception instance and all its causes irreversibly

    Parameters:
      `t` - a throwable
    Returns:
      The root cause exception instances, with stack trace modified to filter out groovy runtime classes
