    ArrayIndexOutOfBoundsException has nothing to do with RMI. Neither does 880 yards of Swing code. You really need to learn to read a stack trace, and how to distinguish relevance from irrelevance Commented Mar 21, 2015 at 23:00

Reset to default

ArrayIndexOutOfBoundsException: 3

and

tp_port[i]

i is 3, and tp_port[] only has 3 or fewer elements.

@shinjw Lest the OP and future readers be confused, there is no guessing here whatsoever. It follows directly from the exception. If the OP hadn't posted half a mile of 99% irrelevant code I might have delved further into the underlying cause.
Totally misphrased that. Did not mean to use the word guess. OP made an insightful question. And you provided clear and concise answer.
