Normal Groovy allows Closure elements of Map instances to be called using method call syntax. That is, the following is valid Groovy:
def m = [ f: { return 'hello' } ]
println m.f()
However, this is rejected by the sandbox:
groovy.lang.MissingMethodException: No signature of method: java.util.LinkedHashMap.f() is applicable for argument types: () values: [] Possible solutions: is(java.lang.Object), find(), any(), get(java.lang.Object), get(java.lang.Object), get(java.lang.Object) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SandboxInterceptor.onMethodCall(SandboxInterceptor.java:131) at org.kohsuke.groovy.sandbox.impl.Checker$1.call(Checker.java:155) at org.kohsuke.groovy.sandbox.impl.Checker.checkedCall(Checker.java:159) at org.kohsuke.groovy.sandbox.impl.Checker$checkedCall.callStatic(Unknown Source) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCallStatic(CallSiteArray.java:56) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callStatic(AbstractCallSite.java:194) at Script1.run(Script1.groovy:4) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.GroovySandbox.run(GroovySandbox.java:141) at org.jenkinsci.plugins.scriptsecurity.sandbox.groovy.SecureGroovyScript.evaluate(SecureGroovyScript.java:333) at hudson.plugins.groovy.SystemGroovy.run(SystemGroovy.java:95) at hudson.plugins.groovy.SystemGroovy.perform(SystemGroovy.java:59) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:20) at hudson.model.AbstractBuild$AbstractBuildExecution.perform(AbstractBuild.java:779) at hudson.model.Build$BuildExecution.build(Build.java:205) at hudson.model.Build$BuildExecution.doRun(Build.java:162) at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:534) at hudson.model.Run.execute(Run.java:1741) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:43) at hudson.model.ResourceController.execute(ResourceController.java:98) at hudson.model.Executor.run(Executor.java:410)
Note that the more explicit (m.f)() and m['f']() work just fine.
