问题
I've been using neo4j 1.9 RC1 for the past two months. Yesterday, after an eclipse crash I started having this this exception:
Exception in thread "main" java.lang.RuntimeException: org.neo4j.kernel.lifecycle.LifecycleException: Component 'org.neo4j.kernel.impl.transaction.TxManager@bf5743' was successfully initialized, but failed to start. Please see attached cause exception.

I am running it with Java 1.7. Any ideas?
回答1:
It seems that your data directory is corrupt. There is already a suggestion printed to the log to fix that issue:
