Document

Validate an argument, throwing IllegalArgumentException if the test result is false.

This is used when validating according to an arbitrary boolean expression, such as validating a primitive number or using your own custom validation expression.

 Validate.isTrue( i > 0 ); Validate.isTrue( myObject.isOk() ); 

The message in the exception is 'The validated expression is false'.
