> Expression Lambdas cannot be debugged
> -
>
> Key: NETBEANS-3580
> URL: https://issues.apache.org/jira/browse/NETBEANS-3580
> Project: NetBeans
> Issue Type: Improvement
> Components: debugger - Java
>Affects Versions: 11.2, 11.3
>Reporter: Jan Lahoda
>Assignee: Akhilesh Singh
>Priority: Critical
> Labels: debug, lambda
>
> Consider this source code:
> {{package org.netbeans.modules.learning.lambda.code.completion;}}
> {{import java.util.Arrays;}}
> {{public class NewClass {}}
> {{ public static void main(String... args) {}}
> {{ Arrays.stream(new String[] \{"a", "", "b"})}}
> {{ .filter(s -> !s.isEmpty()) //breakpoint here}}
> {{ .forEach(System.err::println);}}
> \{{ }}}
> {{}}}
>
> Add a breakpoint at the marked line, and run the code under the debugger. The
> debugger will stop on the breakpoint for the "filter" method invocation (OK),
> but it will not stop there for the lambda invocation (bad). So with a code
> like this, one does not see the lambda parameters, cannot step inside, etc.
> Workaround is to place the expression on a new line:
> {\{ .filter(s -> }}
> \{{ !s.isEmpty()) //breakpoint here}}
> But that requires a change to the code just for debugging - and that defies
> the purpose of debugging (which is to inspect the code *without* changes).
> The IDE is a fully updated Apache NetBeans 11.2, with nb-javac installed
> running on JDK 13:
> Product Version: Apache NetBeans IDE 11.2
> Java: 13.0.1; OpenJDK 64-Bit Server VM 13.0.1+9
> Runtime: OpenJDK Runtime Environment 13.0.1+9
> System: Linux version 4.15.0-72-generic running on amd64; UTF-8; en_US (nb)
> User directory: /tmp/nbuser.lambda.test
> Cache directory: /tmp/nbuser.lambda.test/var/cache
