Description

When I compile the following code

UnsupportedOperator.groovy

@groovy.transform.CompileStatic  
class UnsupportedOperator { 
  def x = 'a' !== 'b' 
} 

I get the following NullPointerException during compilation:

BUG! exception in phase 'instruction selection' in source unit 'ConsoleScript13' unexpected NullpointerException

Caused by: java.lang.NullPointerException

Without the @CompileStatic, I get the expected error message:

Caused by: org.codehaus.groovy.syntax.SyntaxException: Operator ("!==" at 3:17:  "!==" ) not supported @ line 3, column 17.

This might be similar to https://github.com/groovy/groovy-eclipse/issues/179
