040803 custom, 1.5.0 b60, Ocean. When I invoke
Java code completion and get the popup Javadoc,
approximately every second the selection of member
in the popup list is reset to the first item, and
the popup Javadoc is reset to the Javadoc for the
first item (flashing in case it was already on the
first item). For example, if I type

  return System.i
                 ^
                 +- CARET HERE

and press Ctrl-SPACE, I get "in" and
"identityHashCode" in the list as expected. Popup
Javadoc for "in" is displayed and flashes once a
second. If I press Down or Page Down, I very
briefly see Javadoc for identityHashCode(), but it
almost immediately resets to that for System.in.

Makes code completion unusable. Observed for the
first time in this build, I think.
