This sounds very implausible, because the UUID(long)-constructor calls the
UUIS(String)-constructor. But the UUID(String)-constructor seems very
weird. Look at this:

public UUID(String stringValue, boolean shortUUID) {
 int length = stringValue.length();
 if (shortUUID) {
  if (length < 1 || length > 8)
   throw new IllegalArgumentException();
  // How does this look to you?
  init("00000000".substring(length) + stringValue +
   "00001000800000805F9B34FB");
 } else {
  if (length < 1 || length > 32)
   throw new IllegalArgumentException();

init("00000000000000000000000000000000".substring(length)
   + stringValue);
 }
}

As of version BlueCove 2.0.1 we are running JSR-82 TCK. There are no errors 
reported
in the tests related to UUID constructors.
