The eclipse code formatter adds a trailing space in each empty Javadoc comment line (see screenshot).
I found that if you go to Preferences → Java → Editor → Content Assist → Save Actions
the following configuration works most of the time:
(That is to say, turn off the Format source code
option in Save Actions
, but keep the Remove trailing white spaces on all lines
in Additional actions
on.)
The formatter and save actions duke it out, but save actions seems to win most of the time. The downside of this is that you need to periodically manually format the code.
This is using Eclipse Juno.
