Can you show the code where this error originated from?

manjeet1198 commented 8 years ago

public class className{ public static Database getDB() { try (Env env = new Env("/tmp/mydb")) { try (Database db = env.openDatabase()) { return db; } } } }

from main() , Database db = className.getDB() ; db.put(bytes("Tampa"), bytes("rocks"));

You are closing both Env and Database as you return from the try-with-resources code block in getDB method.
