Description

When executing the code:

#! /usr/bin/env groovy

import groovy.sql.DataSet
import groovy.sql.Sql

@Grab ( 'org.xerial:sqlite-jdbc:3.7.2' )
@GrabConfig ( systemClassLoader = true )
def database
final words = [ ]
try {
  database = Sql.newInstance ( 'jdbc:sqlite:database.db' , 'org.sqlite.JDBC' )
  final wordsTable = new DataSet ( database , 'words' )
  ( 0 ..< 4 ).each { i ->
    words << wordsTable.findAll ( { j , item -> item.id == j }.curry ( i ) ).firstRow ( ).word
  }
}
finally {
  database?.close ( )
}
println words.join ( '' )

the result is the error:

Caught: groovy.lang.GroovyRuntimeException: Could not find the ClassNode for MetaClass: groovy.lang.MetaClassImpl@6c1826dc[class org.codehaus.groovy.runtime.CurriedClosure]
groovy.lang.GroovyRuntimeException: Could not find the ClassNode for MetaClass: groovy.lang.MetaClassImpl@6c1826dc[class org.codehaus.groovy.runtime.CurriedClosure]

which doesn't really tell the programmer anything useful about the executed code they wrote.
