[appengine-java] Re: SAXParseException: Premature end of file on dev server
I have got the warning that I reported at the beginning of this thread again today, in the same circumstances. I have the index file datastore-indexes-auto.xml. I started my run without an index file or a local_db.bin file, so both files were created by the GAE/J development server together. I did stop my server later and then restart it using the same .bin and .xml files, and then got my warning. It might be that the dev server caches writes and that the index file got updated but not the datastore file before I shut the server down. But in this case, I fail to see how, on server restart, a required index already added to the index file automatically should cause a problem. This is a low priority note, but it would be nice to clear it up (just as I like to clear all compilation warnings!).

I just got this error again, but instead of just the one line I reported at the head of this thread, this exception caused the failure of the creation of my (next) Apache Wicket page. I set out the full stack trace for interested people below. Ignore the Wicket part of it, since I believe that the Wicket failure is caused by a preceding SAXParseException. As a work-around, I just went to the previous page using my browser and tried again.

Re: [appengine-java] Re: SAXParseException: Premature end of file on dev server
I got this error several times. In my case, error was coming from data xml files used to upload data. The xml files were containing bad chars because they had been edited with an inappropriate text editor. Yep, I know, this surely doesn't help...
