Tomcat - SAXParseException - 序言中不允许内容 - 仅在 Debian Docker 映像中出现问题

问题描述

我在使用 SAXParseException docker image 时得到 bitnami/tomcat:7 (debian) 但在使用 docker.io/hobsonspipe/centos-tomcat7 图像时它工作正常。我什至使用相同的 java jdk1.8.0_131

进行了测试

我还使用 xmllint 测试了 xml，没有错误。

<?xml version="1.0" encoding="utf-8"?>

图片之间有什么区别？我在日志中报告的第一行没有看到任何隐藏字符。
