Small bug and fix starting SQL Developer on Mac OS X

Question

I couldn't find anyone else mentioning this so I'll write it in.
If I started SQL Developer in one user I couldn't start it again in another user, even after quitting out of the first. I would double click the icon and it would do the animated "zoom" but then nothing.
I tracked it down to a problem in SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh. When it redirects the output of the call to the start scipt in the /sqldeveloper/bin directory it would fail because the /tmp/sqldeveloper-startup.log was owned by the first user to start the App (since the /tmp was cleared anyway). My umask didn't give it permission to start overwriting that file.
To fix it I changed the last line in SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh to:
bash ./sqldeveloper >/tmp/sqldeveloper-startup.$$.log
so that the PID was now part of the name and each initiation of SQL Developer would have its own.
You could also change the last line to:
bash ./sqldeveloper >$(mktemp /tmp/sqldeveloper-startup.log.XXXXX)
which would guarantee more uniqueness but wouldn't let you know which process was using the file.
Savvy Mac users can edit the script themselves by right-clicking on the SQLDeveloper.app and selecting "Show Package Contents". You may have to temporarily change the file permissions to let you edit it.
For the record I'm running SQL Developer 1.2.0 on a Mac TiBook G4 867MHz with Mac OS X 10.4.10 and 1Gb RAM (and it is still maddeningly slow because Java fundamentally sucks).

Ok - I think I found it.
Go into ~/Library/Application Support/SQL Developer/system1.5.3.57.83/o.ide.11.1.1.0.22.49.44 (or similar for whatever version you're running) and edit the settings.xml file there.
Look for a block that looks like:
<Item class="oracle.javatools.util.Pair">
<first class="java.lang.String">delete-previous</first>
<second class="oracle.ide.keyboard.KeyStrokes">
<data>
<Item class="javax.swing.KeyStroke">[0]</Item>
</data>
</second>
</Item>
and change it to:
<Item class="oracle.javatools.util.Pair">
<first class="java.lang.String">delete-previous</first>
<second class="oracle.ide.keyboard.KeyStrokes">
<data>
<Item class="javax.swing.KeyStroke">[8]</Item>
</data>
</second>
</Item>
I'm not sure why, but this file seems to always contain the incorrect keystroke value when I do a fresh install of SQL Developer. I always have to go in and change that value by hand. I've tried choosing any number of the accelerator presets, but none of them make the delete key work.
