Support for the "headless" JVM property -- -Djava.awt.headless=true -- on
iSeries is recently available, but for V5R2 only.  (You will need to get
the PTFs that include support for JDK1.4.1 -- the group PTF update should
be out in a day or two.)

JDK1.4 is available on V5R1 (JDK1.4.0 for now, with 1.4.1 coming Real Soon
New) but the headless property is NOT supported in V5R1.  Equivalent
"headless" functionality is available using NAWT in V5R1, which is the
Right Answer.

Nobody wants to use RAWT unless they have to (whenever there are
interactive "headed" graphics requirements in V5R1 and earlier releases.)

For V5R2, all graphics applications deployed using JDK 1.4 should migrate
to using NAWT instead of RAWT.

HTH.
