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 -
Returns:
The exception passed in, after cleaning the 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 -
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 -
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 -
Returns:
The root cause exception instances, with stack trace modified to filter out groovy runtime classes
