Java8 方法引用的 Proguard 混淆在运行时中断

2023-11-30

我在混淆 java8 源代码时遇到了一个持续存在的问题。当 Lambda 方法引用在函数中多次使用时，它们似乎会在运行时失败。失败的代码：

Set<String> roleNames = this.userDAO.getUserRoles(userDTO.getId()).stream().map(RoleDTO::getName).collect(Collectors.toSet());
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo(roleNames);

Set<String> permissions = this.userDAO.getUserPermissions(userDTO.getId()).stream().map(NameDescriptionDTO::getName).collect(Collectors.toSet());
authorizationInfo.addStringPermissions(permissions);

当使用 maven 和 java 8.0_40 编译时，这可以正常工作，但是当 proguard 使用以下堆栈跟踪混淆库时，这会失败：

org.jboss.weld.interceptor.proxy.InterceptorException: java.lang.BootstrapMethodError: call site initialization exception
~
Caused by: java.lang.invoke.LambdaConversionException: Invalid receiver type class package.db.dto.PermissionDTO; not a subtype of implementation type class package.db.dto.RoleDTO

at package.method(Unknown Source) ~[LIB.jar:?]

proguard-maven-插件设置：

<options>
    <option>-dontshrink</option>
    <option>-dontoptimize</option>
    <option>-keepdirectories</option>
    <option>-keepattributes Signature</option>
    <option>-keepattributes *Annotation*</option>
    <option>-keep public class * implements Foo</option>
    <option>-keepclassmembers,allowshrinking,allowobfuscation class * { synthetic &lt;methods&gt;; }</option>
</options>

重写代码以使用 lambda 表达式而不是方法引用格式似乎确实可行，但由于我在整个源代码的许多地方使用方法引用，这只是最后的解决方案：

Set<String> roleNames = this.userDAO.getRoles(userDTO.getId()).stream().map(r -> r.getName()).collect(Collectors.toSet());   
Set<String> permissions = this.userDAO.getPermissions(userDTO.getId()).stream().map(p -> p.getName()).collect(Collectors.toSet());

我调查了错误消息，似乎存在 JVM bug（带有泛型的 LambdaConversionException：JVM 错误？）这可能是相关的。使用cfr_0_98反编译混淆和未混淆的java文件没有显示任何明显的差异：混淆输出：

Set set = this.userDAO.a(userDTO.getId()).stream().map((Function<package.db.dto.RoleDTO, String>)LambdaMetafactory.metafactory(null, null, null, (Ljava/lang/Object;)Ljava/lang/Object;, getName(), (package/db/dto/RoleDTO;)Ljava/lang/String;)()).collect(Collectors.toSet());
Set set2 = this.userDAO.c(userDTO.getId()).stream().map((Function<package.db.dto.PermissionDTO, String>)LambdaMetafactory.metafactory(null, null, null, (Ljava/lang/Object;)Ljava/lang/Object;, getName(), (Lpackage /db/dto/PermissionDTO;)Ljava/lang/String;)()).collect(Collectors.toSet());

未混淆的输出（来自其他机器现在更具可读性并且也显示了问题。RoleDTO 被错误地使用了 2 次！）：

Set set = this.userDAO.a(userDTO.getId()).stream().map(RoleDTO::getName).collect(Collectors.toSet());
Set set2 = this.userDAO.c(userDTO.getId()).stream().map(RoleDTO::getName).collect(Collectors.toSet());

如果有任何关于 Proguard 标志可以帮助我们的指示，我们将不胜感激。

Edit:

这是反汇编的混淆字节码（javap -v）：

Update

我们已经搬到http://www.zelix.com/klassmaster/为了我们的混淆。商业版，但它确实可以很好地与所有 Java 8 功能配合使用。（我不隶属）。

在原来的BootstrapMethods属性

BootstrapMethods:
    0: #141 invokestatic java/lang/invoke/LambdaMetafactory.metafactory:(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite;
      Method arguments:
        #142 (Ljava/lang/Object;)Ljava/lang/Object;
        #143 invokevirtual package/db/dto/RoleDTO.getName:()Ljava/lang/String;
        #144 (Lpackage/db/dto/RoleDTO;)Ljava/lang/String;
    1: #141 invokestatic java/lang/invoke/LambdaMetafactory.metafactory:(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite;
      Method arguments:
        #142 (Ljava/lang/Object;)Ljava/lang/Object;
        #155 invokevirtual package/db/dto/NameDescriptionDTO.getName:()Ljava/lang/String;
        #156 (Lpackage/db/dto/PermissionDTO;)Ljava/lang/String;

两个条目都指向不同的目标方法。你看清楚了#143 invokevirtual … RoleDTO.getName and #155 invokevirtual … NameDescriptionDTO.getName;这两个参数对应于implMethodbootstrap方法的参数

metafactory(caller, invokedName, invokedType, samMethodType, implMethod, instantiatedMethodType)

相反，在混淆类中’BootstrapMethods属性

  BootstrapMethods:
    0: #63 invokestatic java/lang/invoke/LambdaMetafactory.metafactory:(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite;
      Method arguments:
        #93 (Ljava/lang/Object;)Ljava/lang/Object;
        #62 invokevirtual package/db/dto/RoleDTO.getName:()Ljava/lang/String;
        #95 (Lpackage/db/dto/RoleDTO;)Ljava/lang/String;
    1: #63 invokestatic java/lang/invoke/LambdaMetafactory.metafactory:(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite;
      Method arguments:
        #93 (Ljava/lang/Object;)Ljava/lang/Object;
        #62 invokevirtual package/db/dto/RoleDTO.getName:()Ljava/lang/String;
        #94 (Lpackage/db/dto/PermissionDTO;)Ljava/lang/String;

两个条目都引用完全相同的目标方法#62 invokevirtual … RoleDTO.getName.

所以混淆器在这里做了语义改变转换，我猜这是 Proguard 中的一个 bug。 JRE 拒绝调用是正确的，因为最后一个条目仍然请求功能签名(PermissionDTO)String但想将其链接到目标方法RoleDTO.getName其具有功能签名(RoleDTO)String and PermissionDTO不能分配给RoleDTO（这正是消息所说的）。
