dev-java/jansi-1.1 is in the tree. 1.9 is now in java-overlay. It seems to have changed a lot. It now requires jansi-native, which is also in java-overlay. The native code only appears to be necessary for Windows but this package is still required. This is needed for CraftBukkit (Minecraft) and the new version of jline.
