Lambda in security manager initialization fail (original) (raw)

I have a customized security manager:

import java.security.AccessController; import java.security.PrivilegedAction;

public class A3 extends SecurityManager { public A3() { // 1. Using lambda AccessController.doPrivileged((PrivilegedAction) () -> null); // 2. Using inner class AccessController.doPrivileged(new PrivilegedAction() { @Override public Void run() { return null; } }); } }

If I use the inner class, everything is OK. If the lambda, I see this error:

$ java -Djava.security.manager=A3 Error occurred during initialization of VM java.lang.ExceptionInInitializerError at java.lang.invoke.BoundMethodHandle.(BoundMethodHandle.java:829) at java.lang.invoke.LambdaForm.createIdentityForms(LambdaForm.java:1753) at java.lang.invoke.LambdaForm.(LambdaForm.java:1808) at java.lang.invoke.DirectMethodHandle.makePreparedLambdaForm(DirectMethodHandle.java:223) at java.lang.invoke.DirectMethodHandle.preparedLambdaForm(DirectMethodHandle.java:188) at java.lang.invoke.DirectMethodHandle.preparedLambdaForm(DirectMethodHandle.java:177) at java.lang.invoke.DirectMethodHandle.make(DirectMethodHandle.java:84) at java.lang.invoke.MethodHandles$Lookup.getDirectMethodCommon(MethodHandles.java:1655) at java.lang.invoke.MethodHandles$Lookup.getDirectMethodNoSecurityManager(MethodHandles.java:1612) at java.lang.invoke.MethodHandles$Lookup.getDirectMethodForConstant(MethodHandles.java:1797) at java.lang.invoke.MethodHandles$Lookup.linkMethodHandleConstant(MethodHandles.java:1746) at java.lang.invoke.MethodHandleNatives.linkMethodHandleConstant(MethodHandleNatives.java:477) at A3.(A3.java:6) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:444) at sun.misc.Launcher.(Launcher.java:96) at sun.misc.Launcher.(Launcher.java:57) at java.lang.ClassLoader.initSystemClassLoader(ClassLoader.java:1440) at java.lang.ClassLoader.getSystemClassLoader(ClassLoader.java:1425) Caused by: java.lang.NullPointerException at sun.invoke.util.BytecodeDescriptor.parseSig(BytecodeDescriptor.java:83) at sun.invoke.util.BytecodeDescriptor.parseMethod(BytecodeDescriptor.java:54) at sun.invoke.util.BytecodeDescriptor.parseMethod(BytecodeDescriptor.java:41) at java.lang.invoke.MethodType.fromMethodDescriptorString(MethodType.java:1065) at java.lang.invoke.BoundMethodHandle$Factory.makeCbmhCtor(BoundMethodHandle.java:817) at java.lang.invoke.BoundMethodHandle$Factory.makeCtors(BoundMethodHandle.java:772) at java.lang.invoke.BoundMethodHandle$SpeciesData.initForBootstrap(BoundMethodHandle.java:358) at java.lang.invoke.BoundMethodHandle$SpeciesData.(BoundMethodHandle.java:447) at java.lang.invoke.BoundMethodHandle.(BoundMethodHandle.java:829) at java.lang.invoke.LambdaForm.createIdentityForms(LambdaForm.java:1753) at java.lang.invoke.LambdaForm.(LambdaForm.java:1808) at java.lang.invoke.DirectMethodHandle.makePreparedLambdaForm(DirectMethodHandle.java:223) at java.lang.invoke.DirectMethodHandle.preparedLambdaForm(DirectMethodHandle.java:188) at java.lang.invoke.DirectMethodHandle.preparedLambdaForm(DirectMethodHandle.java:177) at java.lang.invoke.DirectMethodHandle.make(DirectMethodHandle.java:84) at java.lang.invoke.MethodHandles$Lookup.getDirectMethodCommon(MethodHandles.java:1655) at java.lang.invoke.MethodHandles$Lookup.getDirectMethodNoSecurityManager(MethodHandles.java:1612) at java.lang.invoke.MethodHandles$Lookup.getDirectMethodForConstant(MethodHandles.java:1797) at java.lang.invoke.MethodHandles$Lookup.linkMethodHandleConstant(MethodHandles.java:1746) at java.lang.invoke.MethodHandleNatives.linkMethodHandleConstant(MethodHandleNatives.java:477) at A3.(A3.java:6) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at java.lang.Class.newInstance(Class.java:444)

Any reason why?
