java - 伯克利DB在GAE上

我正在尝试在GAE上使用Berkely DB，除了日志记录之外，其他一切都正常。这是代码片段

EnvironmentConfig envConfig = new EnvironmentConfig();
        envConfig.setAllowCreate(allowCreateNew);
        envConfig.setConfigParam(EnvironmentConfig.FILE_LOGGING_LEVEL, "OFF");
        envConfig.setConfigParam(EnvironmentConfig.CONSOLE_LOGGING_LEVEL, "OFF");
        envConfig.setLoggingHandler(null);
        envConfig.setReadOnly(isReadOnly);
        envConfig.setTransactional(false);
        if (cacheSize != null)
            envConfig.setCacheSize(cacheSize);
        env = new Environment(dbPath, envConfig);

可以看出，我已禁用日志记录，而GAE上的logging.properties文件是

.level = WARNING
handlers = java.util.logging.ConsoleHandler
java.util.logging.ConsoleHandler.level=OFF
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

# Set the default logging level for ORM, specifically, to WARNING
DataNucleus.JDO.level=WARNING
DataNucleus.Persistence.level=WARNING
DataNucleus.Cache.level=WARNING
DataNucleus.MetaData.level=WARNING
DataNucleus.General.level=WARNING
DataNucleus.Utility.level=WARNING
DataNucleus.Transaction.level=WARNING
DataNucleus.Datastore.level=WARNING
DataNucleus.ClassLoading.level=WARNING
DataNucleus.Plugin.level=WARNING
DataNucleus.ValueGeneration.level=WARNING
DataNucleus.Enhancer.level=WARNING
DataNucleus.SchemaTool.level=WARNING
java.sql.level=WARNING

我遵循了其他人从stackoverflow给出的所有指针，但是我仍然在

java.lang.NoClassDefFoundError: java.util.logging.ConsoleHandler is a restricted class. Please see the Google  App Engine developer's guide for more details.

任何有关如何从Berkley DB禁用日志记录的指针将不胜感激！

最佳答案

看起来com.sleepycat.je.utilint.LoggerUtils .getLogger方法始终尝试在根记录器上安装处理程序（如果不存在）。具体来说，它正在尝试安装：


java.util.logging.ConsoleHandler
com.sleepycat.je.utilint.ConsoleRedirectHandler
com.sleepycat.je.utilint.FileRedirectHandler
com.sleepycat.je.utilint.ConfiguredRedirectHandler


更改日志记录配置不会阻止代码尝试执行此操作。

似乎确实应该对com.sleepycat.je.utilint.LoggerUtils进行修补，以处理addHandlers和NoClassDefFoundError引发的SecurityException，以扩展受限制的类。
