I cannot confirm that the bug doesn't occur with jEdit in Unity 2D. Using the latest Oneiric daily build with Unity 4.4.0 and Unity 2D 3.8.10 I was able to reproduce the problem following the aforementioned steps .
However, it should be noted that the bug only appears with jEdit 4.3.2 from the repository. The recently released version 4.4.1 of jEdit which can be obtained from http://sourceforge.net/projects/jedit/files/jedit/4.4.1/ includes a fix for the launcher bug. See change log at http://jedit.org/CHANGES44.txt (last bullet point under version 4.4.1).
Although jEdit works in its latest version that does not necessarily mean that other Java based programs are not affected by this bug.
