Description

This code:

@groovy.transform.CompileStatic
class Test {
  long[] data
  long topMask
    
  void doSomething() {
    long mask = 0
    mask = mask | 0x1L
    data[ 0 ] = data[ 0 ] | mask
  }
}

new Test()

Gives the error:

[Static type checking] - Cannot assign value of type java.lang.Number to variable of type long

A workaround is to add a cast:

    data[ 0 ] = data[ 0 ] | (long)mask

But I think that might cause GROOVY-5921 to rear its head again...
