The following Xtend snippet <T extends Integer> (T,T)=>T genericCastOfFunctionResult() { [T a,T b|(a+(b as Integer)) as T] } is accepted by the Xtend2 editor (i.e. passes validation) but the compiler chokes on it with the following error (displayed in the console): 1557562 [Worker-15] ERROR org.eclipse.xtext.xtend2.ui.builder.Xtend2BuilderParticipant - Error compiling platform:/resource/test/src/Test.xtend java.lang.IllegalArgumentException: argument may not be null if parameters have to be replaced by wildcards at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.serialize(AbstractXbaseCompiler.java:190) at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.serialize(AbstractXbaseCompiler.java:146) at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.serialize(AbstractXbaseCompiler.java:143) at org.eclipse.xtext.xbase.compiler.TypeConvertingCompiler.convertPrimitiveToWrapper(TypeConvertingCompiler.java:185) at org.eclipse.xtext.xbase.compiler.TypeConvertingCompiler.doConversion(TypeConvertingCompiler.java:77) at org.eclipse.xtext.xbase.compiler.TypeConvertingCompiler.internalToConvertedExpression(TypeConvertingCompiler.java:58) at org.eclipse.xtext.xbase.compiler.XbaseCompiler._toJavaExpression(XbaseCompiler.java:310) at sun.reflect.GeneratedMethodAccessor235.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.xtext.util.PolymorphicDispatcher.invoke(PolymorphicDispatcher.java:291) at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.internalToJavaExpression(AbstractXbaseCompiler.java:121) at org.eclipse.xtext.xbase.compiler.TypeConvertingCompiler.internalToConvertedExpression(TypeConvertingCompiler.java:71) at org.eclipse.xtext.xbase.compiler.TypeConvertingCompiler.internalToJavaExpression(TypeConvertingCompiler.java:50) at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.compile(AbstractXbaseCompiler.java:97) at org.eclipse.xtext.xbase.compiler.XbaseCompiler._toJavaStatement(XbaseCompiler.java:504) at org.eclipse.xtext.xtend2.compiler.Xtend2Compiler._toJavaStatement(Xtend2Compiler.java:455) at sun.reflect.GeneratedMethodAccessor229.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.xtext.util.PolymorphicDispatcher.invoke(PolymorphicDispatcher.java:291) at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.internalToJavaStatement(AbstractXbaseCompiler.java:109) at org.eclipse.xtext.xbase.compiler.XbaseCompiler._toJavaStatement(XbaseCompiler.java:52) at sun.reflect.GeneratedMethodAccessor222.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.xtext.util.PolymorphicDispatcher.invoke(PolymorphicDispatcher.java:291) at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.internalToJavaStatement(AbstractXbaseCompiler.java:109) at org.eclipse.xtext.xbase.compiler.AbstractXbaseCompiler.compile(AbstractXbaseCompiler.java:91) at org.eclipse.xtext.xtend2.compiler.Xtend2Compiler.compile(Xtend2Compiler.java:292) at org.eclipse.xtext.xtend2.compiler.Xtend2Compiler.compile(Xtend2Compiler.java:152) at org.eclipse.xtext.xtend2.compiler.Xtend2Compiler.compile(Xtend2Compiler.java:106) at org.eclipse.xtext.xtend2.ui.builder.Xtend2BuilderParticipant.compile(Xtend2BuilderParticipant.java:142) at org.eclipse.xtext.xtend2.ui.builder.Xtend2BuilderParticipant.processDelta(Xtend2BuilderParticipant.java:111) at org.eclipse.xtext.xtend2.ui.builder.Xtend2BuilderParticipant.build(Xtend2BuilderParticipant.java:75) at org.eclipse.xtext.builder.impl.RegistryBuilderParticipant.build(RegistryBuilderParticipant.java:60) at org.eclipse.xtext.builder.impl.XtextBuilder.doBuild(XtextBuilder.java:160) at org.eclipse.xtext.builder.impl.XtextBuilder.incrementalBuild(XtextBuilder.java:141) at org.eclipse.xtext.builder.impl.XtextBuilder.build(XtextBuilder.java:91) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:627) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:170) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:201) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:253) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:256) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:309) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:341) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:140) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:238) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
