Eclipse on FreeBSD - where's my cursor

[jarnold at sydrom.com]

Issue: Eclipse 2.1.x does not show a cursor in the edit pane when editing
java source code [somewhat of an inconvenience]

Background: When using FreeBSD 4.7,4.8 or 4.9, with windowmanagers Gnome,
KDE, fvwm2, whatever, no cursor is visible. Attempting to change the
window behaviour by use of "Window>Preferences>Java>Editor" has no effect.

Alternatively, if I use Jedit, for example, it's fine.

Any thoughts?
