Java tomcat 8问题未显示任何调试错误

我正在使用tomcat 8.5.49，我的logging.properties如下所示：

handlers = 1catalina.org.apache.juli.FileHandler, \
           2localhost.org.apache.juli.FileHandler, \
           3manager.org.apache.juli.FileHandler, \
           java.util.logging.ConsoleHandler

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

# For example, set the org.apache.catalina.util.LifecycleBase logger to log

我使用以下bash脚本启动了tomcat：

#!/bin/sh
export JAVA_HOME=/home/myuser/jdk1.8.0_221
export PATH=$JAVA_HOME/bin:$PATH
export CATALINA_HOME=/home/myuser/tomcat-8.5
export CATALINA_LOG=/home/myuser/tomcat-8.5/logs
export CATALINA_OUT=$CATALINA_LOG
export CATALINA_OPTS="-Djava.awt.headless=true -Xms256m -Xmx512m  -Xss256k -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled"
#export CATALINA_OPTS="-Djava.awt.headless=true -Xms3840m -Xmx5120m -XX:PermSize=256m -XX:MaxPermSize=512m -Xss256k -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled"
export CATALINA_BASE=$CATALINA_HOME
$CATALINA_BASE/bin/startup.sh
date >> /home/myuser/tomcat-8.5/logs/startlog.log

在我的jsp上，我确实有如下内容：

<%@ page isErrorPage="true" import="java.io.*, java.lang.*"%>

    <%
      try{
         //some code
      }catch(Exception e){
         out.println("<div id=\"error\">");
         e.printStackTrace(new java.io.PrintWriter(out));
        out.println("</div>");
      }
    %>

在我运行的JSP上，它显示：

HTTP状态500–内部服务器错误

但是我在logs/catalina.out上找不到任何要调试的错误日志

请帮忙。谢谢

您是否也检查了日志/localhost.log？偶尔，一些tomcat错误会出现在本地主机日志中，但不会出现在catalina日志中
