A DESCRIPTION OF THE PROBLEM :
When saving a formatted text document using the RTFEditorKit the alignment will be completely removed even if no changes were made to the underlying document. This is a known bug but I have a fix for the issue. Following the advice of this Google group posting I managed to fix the issue in my own program:
https://groups.google.com/forum/#!topic/comp.lang.java.gui/ZeDb64epi9w

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create an RTFEditorKit and load a rich text file with varying alignment and then save the document.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect the RTFEditorKit to save the alignment.
ACTUAL -
The RTFEditorKit removes the alignment and does not save it at all.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Please see my patched version of the module on GitHub:
