RFR (S) 8222491: jcmd can fail converting UTF8 output to strings

[Schmelter, Ralf]

Hi David,

of course you could just copy the bytes to System.out, but that would not respect the platforms character encoding. 

And since the PrintWriter of System.out has no write(char[], int, int) method, it is probably easier to just convert to a string. At least I've not found a convenience method to pipe a Reader to a PrintWriter using the char[] based methods.

Best regards,
Ralf

Well I agree that the fix addresses the problem that has been described.

But I can't help but think there has to be a simpler way to pipe one 
inputstream into an outputstream without all the intermediary steps - ie 
creating strings. ??

Cheers,
David
