Java7 and Comparison method violates its general contract!

[Meerkatzenwildschwein]

Hi, always I'm using Java7 I get the following exception. I've tried java7-openjdk-64 and oracle 1.7.0_4/64 on Ubuntu/Mint with orientdb 1.0.1 and 1.1.0. The author field in the order by statement is a simple string.

Exception in thread "AWT-EventQueue-0" com.orientechnologies.orient.core.exception.OCommandExecutionException: Error on execution of command: OSQLQuery [text=select * from EbookPropertyItem order by  author desc]
