Question

我正在尝试通过以下方式打开只读环境：

  public Environment getReadOnlyEnvironment(String xodusRoot, String instance) {
    final EnvironmentConfig config = new EnvironmentConfig().
            setLogDataReaderWriterProvider("jetbrains.exodus.io.WatchingFileDataReaderWriterProvider").
            setLogCacheShared(false).
            setMemoryUsagePercentage(10);
    config.setLogLockTimeout(3000);
    Environment env = Environments.newInstance(xodusRoot + instance, config);
    return env;
  }

问题在于它不断抛出此错误：

Caused by: javax.management.InstanceAlreadyExistsException: jetbrains.exodus.env: type=EnvironmentConfig, location=\var\xodus\master
    at com.sun.jmx.mbeanserver.Repository.addMBean(Repository.java:437)

我认为这是bug。要解决此问题，请关闭管理：fork := true, javaOptions ++= Seq( "-Djava.security.krb5.conf=/krb5.conf" )。
