Description

I have the following program

class Test {
  public static void main(String [] args) {
    java.lang.Class<String> lapse = 1;
  }
} 

Actual behavior

The code compiles, but I get the following runtime error:

 Caught: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '1' with class 'java.lang.Integer' to class 'java.lang.Class' due to: java.lang.ClassNotFoundException: 1
org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '1' with class 'java.lang.Integer' to class 'java.lang.Class' due to: java.lang.ClassNotFoundException: 1
    at Test.main(test.groovy:3)

Expected behavior

The code should have been rejected
