RFR: 8321180: Condition for non-latin1 string size too large exception is off by one [v3]

[Roger Riggs]

> In the compact string implementation of non-latin1 (UTF16) strings the length is constrained by VM implementation limit on the size a byte array that can be allocated. To produce a useful exception the implementation checks the string size against the maximum byte array size. The exception message is correct
> 
> "UTF16 String size is " + len + ", should be less than or equal to " + MAX_LENGTH
> 
> The code should match the message, otherwise the exception thrown is: 
> 
> java.lang.OutOfMemoryError: Requested array size exceeds VM limit
