[jruby-dev] [jira] (JRUBY-6828) TypeError when returning non-nil from a proc called from Java by interface

[Uwe Kubosch (JIRA)]

Uwe Kubosch created JRUBY-6828 TypeError when returning non-nil from a proc called from Java by interface Issue Type: Bug Affects Versions: JRuby 1.7.0.pre1, JRuby 1.7.0.pre2 Assignee: Unassigned Components: Embedding, Java Integration Created: 09/Aug/12 5:33 AM Description: We register a proc as an onClickListener and if the proc returns nil everything is OK, but if it returns non-nil we get this error: W/System.err( 1846): org.jruby.exceptions.RaiseException: (TypeError) failed to coerce org.rubototest.multiact.MultiactActivity to void Downgrading to JRuby 1.6.7.2 works, so I would call it a regression. A workaround is to add "; nil" to the end of the block. Here is a stack trace of the call into the proc: W/System.err( 1914): at java.lang.reflect.Constructor.constructNative(Native Method) W/System.err( 1914): at java.lang.reflect.Constructor.newInstance(Constructor.java:417) W/System.err( 1914): at org.jruby.javasupport.JavaConstructor.newInstanceDirect(JavaConstructor.java:275) W/System.err( 1914): at org.jruby.java.invokers.ConstructorInvoker.call(ConstructorInvoker.java:91) W/System.err( 1914): at org.jruby.java.invokers.ConstructorInvoker.call(ConstructorInvoker.java:178) W/System.err( 1914): at org.jruby.runtime.callsite.CachingCallSite.cacheAndCall(CachingCallSite.java:322) W/System.err( 1914): at org.jruby.runtime.callsite.CachingCallSite.callBlock(CachingCallSite.java:178) W/System.err( 1914): at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:182) W/System.err( 1914): at org.jruby.java.proxies.ConcreteJavaProxy$2.call(ConcreteJavaProxy.java:52) W/System.err( 1914): at org.jruby.runtime.callsite.CachingCallSite.cacheAndCall(CachingCallSite.java:322) W/System.err( 1914): at org.jruby.runtime.callsite.CachingCallSite.callBlock(CachingCallSite.java:178) W/System.err( 1914): at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:182) W/System.err( 1914): at org.jruby.RubyClass.newInstance(RubyClass.java:863) W/System.err( 1914): at org.jruby.RubyClass$INVOKER$i$newInstance.call(RubyClass$INVOKER$i$newInstance.gen) W/System.err( 1914): at org.jruby.internal.runtime.methods.JavaMethod$JavaMethodZeroOrOneOrNBlock.call(JavaMethod.java:274) W/System.err( 1914): at org.jruby.java.proxies.ConcreteJavaProxy$3.call(ConcreteJavaProxy.java:148) W/System.err( 1914): at org.jruby.runtime.callsite.CachingCallSite.cacheAndCall(CachingCallSite.java:312) W/System.err( 1914): at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:169) W/System.err( 1914): at org.jruby.ast.CallOneArgNode.interpret(CallOneArgNode.java:57) W/System.err( 1914): at org.jruby.ast.FCallOneArgNode.interpret(FCallOneArgNode.java:36) W/System.err( 1914): at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) W/System.err( 1914): at org.jruby.ast.RescueNode.executeBody(RescueNode.java:226) W/System.err( 1914): at org.jruby.ast.RescueNode.interpretWithJavaExceptions(RescueNode.java:123) W/System.err( 1914): at org.jruby.ast.RescueNode.interpret(RescueNode.java:113) W/System.err( 1914): at org.jruby.ast.BeginNode.interpret(BeginNode.java:83) W/System.err( 1914): at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) W/System.err( 1914): at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) W/System.err( 1914): at org.jruby.evaluator.ASTInterpreter.INTERPRET_BLOCK(ASTInterpreter.java:112) W/System.err( 1914): at org.jruby.runtime.Interpreted19Block.evalBlockBody(Interpreted19Block.java:209) W/System.err( 1914): at org.jruby.runtime.Interpreted19Block.yield(Interpreted19Block.java:197) W/System.err( 1914): at org.jruby.runtime.Interpreted19Block.call(Interpreted19Block.java:128) W/System.err( 1914): at org.jruby.runtime.Block.call(Block.java:89) W/System.err( 1914): at org.jruby.RubyProc.call(RubyProc.java:271) W/System.err( 1914): at org.jruby.RubyProc.call(RubyProc.java:223) W/System.err( 1914): at org.jruby.javasupport.JavaUtil$1.call(JavaUtil.java:237) W/System.err( 1914): at org.jruby.javasupport.util.RuntimeHelpers$MethodMissingMethod.call(RuntimeHelpers.java:489) W/System.err( 1914): at org.jruby.javasupport.util.RuntimeHelpers.callMethodMissing(RuntimeHelpers.java:416) W/System.err( 1914): at org.jruby.RubyClass.finvoke(RubyClass.java:728) W/System.err( 1914): at org.jruby.javasupport.util.RuntimeHelpers.invoke(RuntimeHelpers.java:549) W/System.err( 1914): at org.jruby.javasupport.Java$6.invoke(Java.java:1193) W/System.err( 1914): at $Proxy0.onClick(Native Method) W/System.err( 1914): at android.view.View.performClick(View.java:4084) W/System.err( 1914): at android.view.View$PerformClick.run(View.java:16966) W/System.err( 1914): at android.os.Handler.handleCallback(Handler.java:615) W/System.err( 1914): at android.os.Handler.dispatchMessage(Handler.java:92) W/System.err( 1914): at android.os.Looper.loop(Looper.java:137) W/System.err( 1914): at android.app.ActivityThread.main(ActivityThread.java:4745) W/System.err( 1914): at java.lang.reflect.Method.invokeNative(Native Method) W/System.err( 1914): at java.lang.reflect.Method.invoke(Method.java:511) W/System.err( 1914): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) W/System.err( 1914): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) W/System.err( 1914): at dalvik.system.NativeStart.main(Native Method) Any help is welcome.
