It is not necessary however your reply made me retest, and it works as it were, but it only shows that error, if, I run the program with EmbeddedGraphDatabase and put it in an 100 second sleep(so that it keeps the database open), and then I change it to EmbeddedReadOnlyGraphDatabase and run it again as second program (while first is already running as EmbeddedGraphDatabase). In this case, this second program shows that error. If I run both programs with EmbeddedReadOnlyGraphDatabase, the exact thing happens :) I guess it's the way the second program complains that the index (and/or the database, since it's in the same path) is already in use by the first program.
