Description
I get the following error in my console trying to use maven 1.1.0-SNAPSHOT which gets latest 2.6.

However, when it started, my statistics directory was not there. And while it’s running, here is the ls -ltr:
tmac:sample tgautier$ ls -ltr statistics/ total 0 -rw-r–r– 1 tgautier tgautier 0 Apr 9 09:24 statistics-store-tc.lck -rw-r–r– 1 tgautier tgautier 0 Apr 9 09:24 statistics-buffer-tc.lck
So this warning is either specious, or something else bad is happening as it appears to have done something.

Use any maven project with maven 1.1.0-SNAPSHOT
$ svn co https://svn.terracotta.org/repo/forge/projects/labs/tim-guice $ cd tim-guice $ mvn install $ cd sample
edit pom to change maven version from 1.0.5 to 1.1.0-SNAPSHOT
$ mvn package $ mvn tc:start

The issue here is that H2 isn’t included in the maven deps, so it’s not there when the statistics system is started up. The lock files aren’t created by H2, but by the CVT itself. This is what it says in the server logs when this error happens:
com.tc.statistics.store.exceptions.StatisticsStoreOpenErrorException: Unexpected error while opening the store database.

Added the dependency to the tc-maven-plugin’s pom, you need to reinstall it for this to work.

Retested with Terracotta 2.6-nightly-rev8192, as of 20080414-180425 (Revision 8192 by cruise@rh4mo0 from 2.6), it is working as expected
Steps:
- svn co https://svn.terracotta.org/repo/forge/projects/labs/tim-guice
- cd tim-guice
- mvn install
- cd sample
- edit pom to change maven version from 1.0.5 to 1.1.0-SNAPSHOT
- mvn package
- mvn tc:start
ACtual: Terracotta server started successfully as expected.
