Grails way to configure connection pool other than legacy dbcp

resources.groovy

import com.jolbox.bonecp.BoneCPDataSource
import org.codehaus.groovy.grails.commons.ConfigurationHolder as CH
import org.codehaus.groovy.grails.commons.ApplicationHolder as AH
import com.burtbeckwith.grails.plugin.datasources.DatasourcesBuilder
import grails.util.Environment

beans = {
  def ds = CH.config.dataSource
  def dsClosure = { bean ->
    bean.destroyMethod = 'close'
    username = ds.username
    password = ds.password
    jdbcUrl = ds.url
    driverClass = ds.driverClassName
    disableJMX = true
    logStatementsEnabled = true
  }

  dataSource(BoneCPDataSource, dsClosure)

  def environment = Environment.getCurrent().getName()
  def dateSources = getDataSources().findAll {it.environments.contains(environment)}
  dateSources.each {
    ds = it
    "dataSource_${ds.name}"(BoneCPDataSource, dsClosure)
  }
}

//this code is from DatasourcesGrailsPlugin.loadConfig()
//yeah, I did have to dig in datasources plugin internals to avoid copy-past
private getDataSources() {
  def script = AH.application.classLoader.loadClass('Datasources').newInstance()
  script.run()

  def datasources = script.datasources
  datasources.delegate = new DatasourcesBuilder()
  datasources()

  datasources.delegate.dataSources
}

The Grails JIRA site no longer exists, the issue was migrated to GitHub, here it is:
