Description

This issue was originally reported and fixed by https://netbeans.org/bugzilla/show_bug.cgi?id=253248 in version 8.2 but I can now reproduce it in the nightly builds.

Here are the original repro steps:

1. I place a breakpoint after this line of code: List<Lang> responseForLanguages = new ArrayList<>(section.getLangs());
2. I enter the following in the Variables tab: responseForLanguages.stream().map(lang -> lang.getId())
3. Netbeans responds Unsupported: can not create a new class
