Method Detail

getInvocationException

public static InvocationException getInvocationException(Throwable throwable)

Wraps the given throwable into an InvocationException, if that is necessary.

If the given throwable is already an instance of InvocationException, the given throwable is returned.

Parameters:

throwable - The throwable to wrap inside an InvocationException.

Returns:

The (possibly) wrapped throwable.

getCause

Technically this unwraps the given exception until one of the following happens

• there is no more underlying cause
• an Exception other than InvocationException or one of its subclasses is encountered

This method will return null if and only if the given exception is null.

Parameters:

throwable - The Throwable to get the cause for.

Returns:

The underlying cause.
