resolveExceptionCause

public static Throwable resolveExceptionCause(Throwable t)

Parameters:

Parameters:

t - The original Throwable - ignored if null

Returns:

The effective exception - same as input if not a wrapper

toRuntimeException

public static RuntimeException toRuntimeException(Throwable t,
                                                  boolean peelThrowable)

Converts a thrown generic exception to a RuntimeException

Parameters:

t - The original thrown exception

peelThrowable - Whether to determine the root cause by "peeling" any enclosing exceptions

Returns:

The thrown cause if already a runtime exception, otherwise a runtime exception of the resolved exception as its cause

toRuntimeException

public static RuntimeException toRuntimeException(Throwable t)
