Remove keys from multilevel map in Jenkins groovy

[viraj]

I have multilevel map like :

def someMap = [gen:[type:all], 
 build:[time:6, 
    types:[
      TypeA:[type1:[a:true, b:false, c:true, d:true, e:true], 
             type2:[a:true, b:false, c:true, d:true, e:true]], 
      TypeB:[type1:[a:true, b:false, c:true, d:true, e:true]
             type2:[a:true, b:false, c:true, d:true, e:true]], 
      TypeC:[type1:[a:true, b:false, c:true, d:true, e:true],
             type2:[a:true, b:false, c:true, d:true, e:true]]]]


 I want to remove the some entries from it, say "TypeA" and "TypeB" from 
map *but with Jenkins groovy script I am not able to do so*, with normal 
groovy, i can delete entries with removeAll() or with iterator, Below 
things already tried.

someMap.build.types.keySet().removeAll(['TypeA', 'TypeB', 
'TypeC'].minus('TypeC')))

def iterator = someMap.build.types.entrySet().iterator()
while (iterator.hasNext()) {
  if (iterator.next().key != 'TypeC' ) {
    iterator.remove()
  }
}


but i get the original map with no element removed.
