IllegalArgumentException

public IllegalArgumentException(Throwable cause)

Constructs a IllegalArgumentException using the specified cause Throwable, which may be used to provide additional history, with regards to the root of the problem. It is perfectly valid for this to be null, if the cause of the problem is unknown.

The detail message is automatically constructed from the detail message of the supplied causal exception. If the cause is null, then the detail message will also be null. Otherwise, the detail message of this exception will be that of the causal exception. This makes this constructor very useful for simply wrapping another exception.

Parameters:

cause - the cause of this exception, or null if the cause is unknown.
