我的代码使用org.owasp.esapi 2.2.0.0，但升级到2.2.3.1后，我得到了classnotfoundexception。
我的代码类似于：

Properties esapiProps = new Properties();
  try {
     esapiProps.load( SecurityUtil.class.getResourceAsStream("/ESAPI.properties") );

  } catch (IOException | NullPointerException e) {
     logger.log(Level.SEVERE, "esapi Exception: ", e);
  }
  ESAPI.override( new DefaultSecurityConfiguration(esapiProps));
  // ----- Then canonicalize an input -----
  ESAPI.encoder().canonicalize(input);

我阅读了发行说明并添加了一些属性和esapi java日志
my esapi.properties（类内路径）

ESAPI.printProperties=true
LogLevel=INFO
ESAPI.Encoder=org.owasp.esapi.reference.DefaultEncoder
Encoder.AllowMultipleEncoding=false
Encoder.AllowMixedEncoding=false
Encoder.DefaultCodecList=HTMLEntityCodec,PercentCodec,JavaScriptCodec

ESAPI.Logger=org.owasp.esapi.reference.JavaLogFactory
Logger.ApplicationName=My Test Application
Logger.LogEncodingRequired=false
Logger.LogApplicationName=true
Logger.LogServerIP=true
Logger.LogFileName=ESAPI_logging_file
Logger.MaxLogFileSize=10000000
Logger.UserInfo=true
Logger.ClientInfo=true

我的esapi-java-logging.properties（类路径中）

handlers= java.util.logging.ConsoleHandler
.level= INFO
java.util.logging.ConsoleHandler.level = INFO
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
java.util.logging.SimpleFormatter.format=[%1$tF %1$tT] [%3$-7s] %5$s %n

但我有一个例外：

如果我更改esapi.properties并复制https://raw.githubusercontent.com/esapi/esapi-java-legacy/develop/configuration/esapi/esapi.properties，classnotfoundexception消失，我得到nullpointerexception异常：
