org.apache.tomcat.util.bcel.classfile.ClassFormatException:常量池中的无效字节标记:15-Tomcat 7，JDK不兼容? [英] org.apache.tomcat.util.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15 - Tomcat 7, JDK incompatibilty?

问题描述

我尝试升级到Java8.启动带有Java 7编译的.war文件的tomcat7服务器时，出现下面的神秘错误.

I tried upgrading to Java 8. When starting our tomcat7 server, with a Java 7-compiled .war file, I get the mysteriously error below.

我希望这行得通吗?这篇帖子指出，tomcat 7应该适用于1.6及更高版本. 我不能说是Tomcat的罪魁祸首还是.war.切换出不同的Java版本:

Should I expect this to work? This post says tomcat 7 should work with 1.6 and up. I can't tell if Tomcat is to blame, or the .war. Switching out different Java versions I get:

• 已安装JDK 7.45-可以工作(用于编译.war的相同版本)
• 已安装JDK 7.55-失败如下
• 已安装JDK 8.05-失败，如下所示

是tomcat的罪魁祸首，还是.war?

Is tomcat to blame, or the .war?

推荐答案

我在Tomcat 7.0.26中看到此错误.

I was seeing this error with Tomcat 7.0.26.

To answer your question, Tomcat is to blame: https://issues.apache.org/bugzilla/show_bug.cgi?id=53735

我已将其升级到7.0.53版(根据链接的问题，此修复应在7.0.30及更高版本中进行.)

Upgrading to version 7.0.53 fixed it for me (according to the linked issue, the fix should be in 7.0.30 and later).
