有人能告诉我这个 flex 堆栈跟踪是什么意思吗?我正在使用 BlazeDS 从 flex 调用 java 函数。该类一切正常,但现在我使用 java 版本 1.7.0_21 重新编译了 java 类,它停止工作并引发以下错误事件。请告诉我出了什么问题。
(mx.rpc::Fault)#0
errorID = 0
faultCode = "Server.Processing"
faultDetail = (null)
faultString = "example/HelloWorld : Unsupported major.minor version 51.0 (unable to load class example.HelloWorld)"
message = "faultCode:Server.Processing faultString:'example/HelloWorld : Unsupported major.minor version 51.0 (unable to load class example.HelloWorld)' faultDetail:'null'"

HelloWorld.java
package example;
public class HelloWorld {

public String getHelloWorld() {

}
public float addTwoNumbers(float a, float b)

return a+b;
}
