Java is often called with absolute paths like
/usr/bin/java, which makes this answer useless in some cases, and requires more to make it work in others.
That solution I found requires writing a wrapper shell script that redirects STDERR through a filter removing the offending line. It has to be placed in the
$PATH before the java binary it wraps and be called with plain
which java or similar (or your tool has to be configured to use it)
It relies on the bash ability to create a subshell with parentheses
(command), and redirect java’s STDERR to its STDIN
command1 2> >(command2). Finally, the process in the subshell needs to redirect its filtered input to STDOUT again so that java programs can still use STDERR.
/usr/bin/java "$@" 2> >(grep -v "^Picked up _JAVA_OPTIONS:" >&2)
