The topic http://db.apache.org/derby/docs/dev/devguide/cdevdvlp27715.html, "Booting databases," currently shows the following output:
2008-09-18 16:43:54.992 GMT:
Booting Derby version The Apache Software Foundation - Apache Derby
- 10.5.2.0 - (689064): instance a816c00e-011c-7658-a92a-fffff0cfee85
on database directory C:\sampledb
There is no release 10.5.2.0 (not yet) – this is the result of using a versionnumber string at 10.4.2.0 and having it automatically (and incorrectly) update to 10.5. It's better to just hardcode the actual release number and then update the files post-release. The revision number is release-specific, too.
I'll update it now that we have an actual 10.5.1.1 release
Various other topics, mostly in Getting Started, have the 10.4.2.0 version and revision number hardcoded. It's time to update these, in the trunk at least.
