Subject [jira] Commented: (DERBY-4907) EmbeddedXADataSource with ;create=true attribute set in setDatabaseName fails with java.sql.SQLException: Database not available

Tiago R. Espinha commented on DERBY-4907:
-----------------------------------------

Hi Siddharth,

I've skimmed through the patch and it looks good, but I have one remark. When you submit a
patch, try to avoid white-space changes like the second change in your latest patch. As you
can see, the only difference is that you added a tab character in front of the bracket, which
makes svn pick it up as a change and makes it harder to review the patch.

There's a few more cases like:
-        xa.close();
+        xa.close();         
(again, the same situation with the tab)

It's a cosmetic thing but especially with large patches, it does matter for whoever's reviewing
it.

I will give the patch a better look later today, once I get home.

Thanks
