类文件常量池（javap）中的方法签名和描述符(Method signatures and descriptors in class file constant pool (javap))

 我试图找出类文件中常量池部分下面的以下两个条目： 
 
int foo(int x) {
    return x;
}

#11 = Utf8               foo
#12 = Utf8               (I)I        // 1   
#13 = Utf8               x
#14 = Utf8               I           // 2
 
 条目（1） - >（I）I表示函数的开始和条目（2） - > I表示函数的结束。 
 
 这个编译器是特定的还是可能因编译器而异？ 
 
 Lambda函数也有类似的问题。 
 
interface I { int foo(int x); }
class X {
I x = (int x1) -> 0;
}

 #15 = Utf8            lambda$new$0
 #16 = Utf8            (I)I
 #17 = Utf8            x1
 #18 = Utf8            I
 
 抱歉在JLS文档上找不到任何内容。 
 
 谢谢 

I am trying to figure out the following two entries under the constant pool section in the class file:
 
int foo(int x) {
    return x;
}

#11 = Utf8               foo
#12 = Utf8               (I)I        // 1   
#13 = Utf8               x
#14 = Utf8               I           // 2
 
Does the entry (1) -> (I)I denotes start of the function and the entry (2) -> I denotes end of function.
 
Is this compiler specific or could vary from one compiler to another?
 
Similar question for Lambda functions as well.
 
interface I { int foo(int x); }
class X {
I x = (int x1) -> 0;
}

 #15 = Utf8            lambda$new$0
 #16 = Utf8            (I)I
 #17 = Utf8            x1
 #18 = Utf8            I
 
Sorry Could not find anything on JLS docs. 
 
Thanks
