XID.toString broken: indexing mistake in array

com.arjuna.ats.internal.jta.xa.XID

public String toString ()
{
//...
stringBuilder.append(", ");
for (int i = 0; i < bqual_length; i++)

{ stringBuilder.append(gtrid_length+data[i]); }

//...
}

correct: stringBuilder.append(data[i+gtrid_length]);

The result is, that the Xid instances logged in log files are corrupted and multiple different Xid share the same String representation, which makes the logging information unusable
