当我编译 java 文件时，在 IntelliJ 项目上出现此错误。没有列出特定的源文件，但它失败并出现此错误。
删除以下编译器标志可修复该错误：
-source 1.5 -target 1.5
然而，这些需要在那里，因为我们的目标是 Java 5。是否有一些特定的代码（也许是try/catch块）导致此错误？

当 try/finally 块出现在源代码中时，JSR/RET 指令就会出现在字节代码中。即使使用 -target 1.5，Javac 1.6+ 似乎也不会发出它们，但 Eclipse java 编译器会发出它们。
Example
public class JSRDemo {
public static void main(String[] args) {
try {
bodyOfTry();
}
finally {
bodyOfFinally();
}
