Test case below

run two times throw above error

@test
public void dbSetFile() {
// configure and open database using builder pattern.
// all options are available with code auto-completion.
DB db = DBMaker.newFileDB(new File("c://testdbset23"))
.closeOnJvmShutdown().transactionDisable()
/* encryptionEnable("password") */.make();

    String setName = "hashSet2";
    Set<Integer> set = null;

    if (!db.exists(setName)) {
        HTreeSetMaker treeSet = db.createHashSet(setName);
        set = treeSet.expireAfterAccess(30, TimeUnit.DAYS).make();
        System.out.println("create");
    } else {
        set = db.getHashSet(setName);
        System.out.println("read exists");
    }

    System.out.println(set.contains(1));
    for (int i = 0; i < 10000; i++)
        set.add(i);

    System.out.println(set.size());
    db.close();

}
