解决方案

嗨这与某些相关应用程序中的字节码。 (请参阅此关于Java 7的兼容性更改的说明,看看JSR 202下面的一些行)



你可以




  • 使用JDK 7重新编译所有来源

  • 或者如果您无权访问源


    • 使用 java with paramter -XX:-UseSplitVerifier

    • 如果您使用开关面对promblems,请切换到Java 6




编辑即使答案已经有点旧了。由于目前的情况,我添加了一些更详细的解释。



类文件中的 StackMapTable 属性是,甚至当时没有记录,在Java 6中引入。



Foo.java

  public class Foo {
public static boolean bar(String s){
if(s.length()== 0){
return true;
}
返回false;
}
}

$ java -version

代码:

10:ireturn
LineNumberTable:
第3行:0
第4行:7
第6行:9

StackMapTable:number_of_entries = 1
frame_type = 9 / *相同* /
}

类验证程序没有检查属性是否在该类是否。



以下创建文件 Foo.class ,不带 StackMatTable 属性。



FooDump.java

  import org.objectweb.asm。*; 
import java.io. *;

公共类FooDump实现操作码{

public static void main(String [] args)抛出异常{
FileOutputStream fos = new FileOutputStream(Foo.class );
fos.write(dump());
fos.close();
}

public static byte [] dump()抛出异常{
ClassWriter cw = new ClassWriter(0);
FieldVisitor fv;

cw.visit(V1_6,ACC_PUBLIC + ACC_SUPER,Foo,null,java / lang / Object,
null);

MethodVisitor mv = cw.visitMethod(ACC_PUBLIC,< init>,()V,null,
null);
mv.visitCode();
mv.visitVarInsn(ALOAD,0);
mv.visitMethodInsn(INVOKESPECIAL,java / lang / Object,< init>,()V,
false);
mv.visitInsn(RETURN);
mv.visitMaxs(1,1);
mv.visitEnd();

mv = cw.visitMethod(ACC_PUBLIC + ACC_STATIC,bar,
(Ljava / lang / String;)Z,null,null);
mv.visitCode();
mv.visitVarInsn(ALOAD,0);
mv.visitMethodInsn(INVOKEVIRTUAL,java / lang / String,length,()I,
false);
Label l0 = new Label();
mv.visitJumpInsn(IFNE,l0);
mv.visitInsn(ICONST_1);
mv.visitInsn(IRETURN);
mv.visitLabel(l0);
//这一行将生成StackMapTable属性
// mv.visitFrame(Opcodes.F_SAME,0,null,0,null);
mv.visitInsn(ICONST_0);
mv.visitInsn(IRETURN);
mv.visitMaxs(1,1);
mv.visitEnd();

cw.visitEnd();
返回cw.toByteArray();
}
}

编译并运行它

  $ javac -cp asm-5.2.jar:asm-util-5.2.jar:。 FooDump.java 
$ java -cp asm-5.2.jar:asm-util-5.2.jar:。 FooDump

检查 StackMapTable 属性是否在文件中

使用Java 7,类验证已更改。



对于类文件版本50(Java 6),如果 StackMapTable 缺失或错误,则检查有故障转移(请参阅:)。



使用 Foo 类Java 6运行检查。

  $ java -version

$ javac FooDemo.java
$ java FooDemo

类文件版本51(Java 7)不再发生此故障转移。



创建 Foo Java 7的类版本修改 FooDump.java 的代码。

  // cw.visit(V1_6,ACC_PUBLIC + ACC_SUPER,Foo,null,java / lang / Object,null); 
cw.visit(V1_7,ACC_PUBLIC + ACC_SUPER,Foo,null,java / lang / Object,null);

你可能会发现一些建议让它运行Java 8 ...

  $ java -noverify FooDemo 
输出:true

$ java -Xverify:none FooDemo
输出:true

note 这会禁用字节码验证程序。请记住。

解决方案

Hi this is related to some bytecode in your application. (see this note on compatibility changes for Java 7 http://www.oracle.com/technetwork/java/javase/compatibility-417013.html#incompatibilities, look there some lines below for JSR 202)

You can either

  • recompile all sources with JDK 7
  • or in case you have no access to the source
    • use java with paramter -XX:-UseSplitVerifier
    • or switch to Java 6 if you face promblems using the switch

edit Even the answer is already a bit old. Because of a current case I add some more detailed explanation.

The StackMapTable attribute in the class file was, even not documented at that time, introduced with Java 6.

Foo.java

public class Foo {
    public static boolean bar(String s) {
        if (s.length() == 0) {
            return true;
        }
        return false;
    }
}

$ java -version
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
$ javac Foo.java
$ javap -c -v Foo
Compiled from "Foo.java"
public class Foo extends java.lang.Object
  SourceFile: "Foo.java"
  minor version: 0
  major version: 50
...
public static boolean bar(java.lang.String);
  Code:
   Stack=1, Locals=1, Args_size=1
   0:   aload_0
   1:   invokevirtual   #2; //Method java/lang/String.length:()I
   4:   ifne    9
   7:   iconst_1
   8:   ireturn
   9:   iconst_0
   10:  ireturn
  LineNumberTable:
   line 3: 0
   line 4: 7
   line 6: 9

  StackMapTable: number_of_entries = 1
   frame_type = 9 /* same */
}

The class verifier did no check if the attribute was in the class or not.

Following creates the file Foo.class without the StackMatTable attribute.

FooDump.java

import org.objectweb.asm.*;
import java.io.*;

public class FooDump implements Opcodes {

    public static void main(String[] args) throws Exception {
        FileOutputStream fos = new FileOutputStream("Foo.class");
        fos.write(dump());
        fos.close();
    }

    public static byte[] dump() throws Exception {
        ClassWriter cw = new ClassWriter(0);
        FieldVisitor fv;

        cw.visit(V1_6, ACC_PUBLIC + ACC_SUPER, "Foo", null, "java/lang/Object",
            null);

        MethodVisitor mv = cw.visitMethod(ACC_PUBLIC, "<init>", "()V", null,
            null);
        mv.visitCode();
        mv.visitVarInsn(ALOAD, 0);
        mv.visitMethodInsn(INVOKESPECIAL, "java/lang/Object", "<init>", "()V",
            false);
        mv.visitInsn(RETURN);
        mv.visitMaxs(1, 1);
        mv.visitEnd();

        mv = cw.visitMethod(ACC_PUBLIC + ACC_STATIC, "bar",
            "(Ljava/lang/String;)Z", null, null);
        mv.visitCode();
        mv.visitVarInsn(ALOAD, 0);
        mv.visitMethodInsn(INVOKEVIRTUAL, "java/lang/String", "length", "()I",
            false);
        Label l0 = new Label();
        mv.visitJumpInsn(IFNE, l0);
        mv.visitInsn(ICONST_1);
        mv.visitInsn(IRETURN);
        mv.visitLabel(l0);
        // this line would generate the StackMapTable attribute
        // mv.visitFrame(Opcodes.F_SAME, 0, null, 0, null);
        mv.visitInsn(ICONST_0);
        mv.visitInsn(IRETURN);
        mv.visitMaxs(1, 1);
        mv.visitEnd();

        cw.visitEnd();
        return cw.toByteArray();
    }
}

compile and run it

$ javac -cp asm-5.2.jar:asm-util-5.2.jar:. FooDump.java
$ java -cp asm-5.2.jar:asm-util-5.2.jar:. FooDump

check that the StackMapTable attribute is not in the file

With Java 7 the class verification was changed.

For class files version 50 (Java 6) the check had a failover if the StackMapTable was missing or wrong (see: jvms-4.10.1).

Run the check with the Foo class version of Java 6.

cw.visit(V1_7, ACC_PUBLIC + ACC_SUPER, "Foo", null, "java/lang/Object", null);
