I have three variants on the same progam/algorithm.
final Future<Double>[] futures = new Future<Double> [ numberOfTasks ] for ( int i in 0i ..< numberOfTasks ) { final taskId = i futures[i] = executor.submit ( new Callable<Double> ( ) { @Override public Double call ( ) { . . . } } ) }
works fine.
final List<Future<Double>> futures = ( 0 ..< numberOfTasks ).collect { taskId
->
executor.submit ( {
. . .
} as Callable )
}
works fine.
final List<Future<Double>> futures = ( 0 ..< numberOfTasks ).collect { taskId -> executor.submit ( new Callable<Double> ( ) { @Override public Double call ( ) { . . . } } ) }
Gives me the error:
Caught: groovy.lang.GroovyRuntimeException: Could not find matching constructor
for: pi_groovy_futures_listNew$1(pi_groovy_futures_listNew,
groovy.lang.Reference, java.lang.Double, java.math.BigDecimal)

So the question is: Why? with a subsidiary: Is it a bug?
There is also the question of course "How the $$$$ to interpret the error message so as to obtain useful information?" :-((
