SOAPUI XmlSlurper memory leak?

Hi,

I have SOAPUI 5.0 installed. My SOAPUI groovy script reads a 18 MB xml file and retrieve xml elements using XMLSlurper. I am seeing the SOAPUI exe grows every time I run the script. It can grow from 30 MB to 100 MB or more... Anyone know what can cause the leak?

This is my script

import groovy.io.FileType

def list = []

def dir = new File("C:\\TEV\\results\\")
dir.eachFileRecurse (FileType.FILES) { file ->
 if (file=~'.xml'){
   f = file.toString().replaceAll("C:\\\\TEV\\\\results\\\\","")
   list << f.toString().replaceAll(".xml","")

 }
}

  list.each{fund->
   def xml = new File( "C:\\TEV\\results\\${fund}.xml" )
   def root = new XmlSlurper().parse(xml)
//   def root = new XmlParser().parse(xml)
   root.holdingGroupList.holdingGroupByWeights.each{hg->

    if (hg.holdingGroupName ==fund){
     log.info ( "${fund} NOTIONAL: ${hg.portfolioValue}")
     def bucket = hg.customBucketList.customBucket
     bucket.each{b ->
      if (b.customDimensionName == 'attribEffect')
       log.info ( "${fund} TAG: ${b.customBucketValue}")
     }
    }
   }

  }
