Excellent! So your program, if you let it, tries to connect to the current DISPLAY then gets all upset if that connection gets removed at a later date.

Great problem determination there!

When you do "ps -ef", there is a column for the controlling terminal (it will either be a real terminal or a pseudo-terminal). Is one still attached to the java process or is it blank?

NAME
tcsetpgrp() - set foreground process group id SYNOPSIS
DESCRIPTION
If the calling process has a controlling terminal, sets the foreground process group ID associated with the terminal referenced by fildes to pgrp_id. The file associated with fildes must be the controlling terminal of the calling process and the controlling terminal must be currently associated with the session of the calling process. The value of pgrp_id must match a process group ID of a process in the same session as the calling process. RETURN VALUE
Upon successful completion, returns zero. Otherwise, returns -1 and sets to indicate the error. ERRORS
fails if any of the following conditions are encountered: [EBADF] fildes is not a valid file descriptor. [EINVAL] The value of the pgrp_id argument is not supported. [ENOTTY] The calling process does not have a controlling terminal, or the fildes is not the controlling terminal, or the con- trolling terminal is no longer associated with the session of the calling process. [EPERM] The value of pgrp_id is a supported value but does not match the process group ID of a process in the same session as the calling process. SEE ALSO
