Gradle Daemon crashes when plugin creates SecurityManager

Hi,

I’ve got a custom plugin (applied with the build script block) that needs to create a SecurityManager in order to perform RMI lookups. When I run the plugin the grade daemon dies and the build crashes. Stack trace follows, any ideas?

* Exception is: org.gradle.launcher.daemon.client.DaemonDisappearedException: Gradle build daemon disappeared unexpectedly (it may have been killed or may have crashed) at org.gradle.launcher.daemon.client.DaemonClient.handleDaemonDisappearance(DaemonClient.java:207) at org.gradle.launcher.daemon.client.DaemonClient.monitorBuild(DaemonClient.java:185) at org.gradle.launcher.daemon.client.DaemonClient.executeBuild(DaemonClient.java:148) at org.gradle.launcher.daemon.client.DaemonClient.execute(DaemonClient.java:117) at org.gradle.launcher.daemon.client.DaemonClient.execute(DaemonClient.java:75) at org.gradle.launcher.cli.RunBuildAction.run(RunBuildAction.java:51) at org.gradle.internal.Actions$RunnableActionAdapter.execute(Actions.java:171) at org.gradle.launcher.cli.CommandLineActionFactory$ParseAndBuildAction.execute(CommandLineActionFactory.java:237) at org.gradle.launcher.cli.CommandLineActionFactory$ParseAndBuildAction.execute(CommandLineActionFactory.java:210) at org.gradle.launcher.cli.JavaRuntimeValidationAction.execute(JavaRuntimeValidationAction.java:35) at org.gradle.launcher.cli.JavaRuntimeValidationAction.execute(JavaRuntimeValidationAction.java:24) at org.gradle.launcher.cli.CommandLineActionFactory$WithLogging.execute(CommandLineActionFactory.java:206) at org.gradle.launcher.cli.CommandLineActionFactory$WithLogging.execute(CommandLineActionFactory.java:169) at org.gradle.launcher.cli.ExceptionReportingAction.execute(ExceptionReportingAction.java:33) at org.gradle.launcher.cli.ExceptionReportingAction.execute(ExceptionReportingAction.java:22) at org.gradle.launcher.Main.doAction(Main.java:33) at org.gradle.launcher.bootstrap.EntryPoint.run(EntryPoint.java:45) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at org.gradle.launcher.bootstrap.ProcessBootstrap.runNoExit(ProcessBootstrap.java:54) at org.gradle.launcher.bootstrap.ProcessBootstrap.run(ProcessBootstrap.java:35) at org.gradle.launcher.GradleMain.main(GradleMain.java:23)

I seem to have fixed this, but a little confused as to why. I had to specify -Djava.security.policy= on the command line, then I could create the SecurityManager without the Gradle daemon crashing.

I had thought that putting java.security.policy= into grade.properties would have sufficed?
