Description

An error occurred when compiling a class of this construction:

import groovy.transform.CompileStatic

class TestCompileStatic {
  Closure func

  @CompileStatic
  void testCallFunc () {
    {color:#d04437}if (func != null) func('test'){color}
  }
}

> BUG! exception in phase 'instruction selection' in source unit 'TestCompileStatic.groovy' unexpected NullpointerException

if you change the code to this:

if (func != null) func.call('test')

then the class is compiled correctly
