Wrong exception in various NumberUtils method documentations

The documentation of various methods in NumberUtils says an IllegalArgumentException is thrown in case of a null argument , e.g., see https://github.com/apache/commons-lang/blob/197d50434748bfb2db935266cfe740fc01a607ee/src/main/java/org/apache/commons/lang3/math/NumberUtils.java#L1194

However, these methods throw a NullPointerException in this case. The following methods are affected:

• long min(final long... array)
• int min(final int... array)
• short min(final short... array)
• byte min(final byte... array)
• static double min(final double... array)
• float min(final float... array)
• long max(final long... array)
• int max(final int... array)
• short max(final short... array)
• byte max(final byte... array)
• double max(final double... array)
• float max(final float... array)
• void validateArray(final Object array)
