Description

With Static Compilation enabled, if I try to call a method declared in a class that receives a parameter of type java.lang.Byte, the compilation fails, returning "[Static type checking] - Cannot find matching method".
The same problem occurs when calling a method from inside another method, for instance:

Test.gvy

@groovy.transform.CompileStatic
void testMethod(java.lang.Byte param){
println(param)
}

@groovy.transform.CompileStatic
void run (){
testMethod(java.lang.Byte.valueOf("123"))
}

run()

The problem seems to be in the "isAssignableTo" method from "org.codehaus.groovy.transform.stc.StaticTypeCheckingSupport.java" class, where ClassHelper.Byte_TYPE doesn't match the type received as an argument, probably because you are not using the redirect() method before comparing with the type that matters.
