Gpars withExistingPool Error jsr166y.ForkJoinPool not found

Question

I have updated from 'org.codehaus.gpars:gpars:1.0.0' to 'org.codehaus.gpars:gpars:1.1.0'. My code works fine in 1.0.0 but in version 1.1.0 I cannot find jsr166y.ForkJoinPool anymore.

How do I get the correct ForkJoinPool?

The code I am using is:

import groovyx.gpars.GParsPool
import jsr166y.ForkJoinPool

class Test {
   def pool = new ForkJoinPool()

   def executeAsync(args, closure = null) {
    if(!closure) {
        closure = args
        args = null
    }

    GParsPool.withExistingPool(pool) {
        closure.callAsync(args)
    }
   }
}

I have to import java.util.concurrent.ForkJoinPool to get the ForkJoinPool class. But at runtime I get the following error:

Update your BuildConfog.groovy as:

compile 'org.codehaus.gpars:gpars:1.1.0'
compile 'org.codehaus.jsr166-mirror:jsr166y:1.7.0'

This should work for you.
