Eclipse compiler issue
Eclipse compiler issue
I am wondering if anyone can help me.
I have an issue with compiling some code in Eclipse but not with IntelliJ or javac.
I am using sneakyThrow to bubble a checked exception up through 2 streams.
Here is the smallest reproducible code I can make:
import java.io.IOException;
import java.util.List;
import java.util.function.Predicate;
import java.util.stream.Collectors;
public class Example {
public static void main(String[] args)
throws IOException {
List<List<Integer>> input = List.of(List.of(1, 2), List.of(2, 4));
// Should return any List whose elements are all even.
List<List<Integer>> output = input.stream()
.filter(bubblePredicate(o -> o.stream()
.allMatch(bubblePredicate(i -> {
if (i > 10) {
throw new IOException("Number too large.");
}
return i % 2 == 0;
}))))
.collect(Collectors.toList());
System.out.println(output);
}
private interface ThrowingPredicate<S, E extends Exception> {
boolean test(S s) throws E;
}
private static <S, E extends Exception> Predicate<S> bubblePredicate(ThrowingPredicate<S, E> callable)
throws E {
return s -> {
try {
return callable.test(s);
}
catch (Exception e) {
sneakyThrow(e);
return false;
}
};
}
private static <E extends Throwable> void sneakyThrow(Exception exception)
throws E {
throw (E)exception;
}
}
Compiles and runs completely fine with javac 11.0.12
, but doesn't on Eclipse 4.21.0.I20210906-0500
nor Eclipse 4.27.0.20230309-1200
.
Has anyone encountered this before, or have any idea what I am misunderstanding?
"Doesn't work", is a fairly useless description of the problem. Does it cause your computer to reboot? Does it spout haiku at you? Are you getting some kind of feedback that might indicate the nature of the problem? If so, you should share it, too.
0 1 ReplyYeah mate, you are right "doesn't work" is pretty useless, lucky I didn't say that
I said I have code that does compile in one specific compiler but doesn't in another specific one, and asked if anyone had ever encountered that before
And 2 days ago when someone mentioned that I didn't include the actual error, I apologised and then included it
