Description

When I run the following codes, I caught
java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.Number
at org.codehaus.groovy.reflection.stdclasses.IntegerCachedClass.coerceArgument(IntegerCachedClass.java:37)
...

def foo(int arg0, String arg1, arg2){
    println arg0
    println arg1
    println arg2
}
foo([ 1, "B", 0.5 ])

but I was able to run the next methods

def foo(Number arg0, String arg1, int arg2){...}

def foo(String arg0, int arg1, int arg2){...}

I tried

  Number GOOD
  String GOOD
  char GOOD
  Object GOOD
  BigInteger GOOD

  int BAD
  BigDecimal BAD
  float BAD
  byte BAD
