which version for jdeveloper 11 stable ?
jdeveloper 11.1.2.3.0
jdeveloper 11.1.2.2.0
jdeveloper 11.1.1.6.0.
jdeveloper 11.1.1.5.0
jdeveloper 11.1.1.4.0

from my point of view

still 11.1.1.4,11.1.1.5 is more stable , however i recommend to up to date, important u follow the updated, solved bugs and avoid big gaps between releases.

Good Luck
