Description kalwi 2016-02-24 10:36:48 UTC 
Java hints are displayed also in case they are not relevant for the configured Java platform version.

E.g. "Can Use Diamond" is wrongly displayed also when the project is configured to use JDK 1.6 platform/sources format, "Convert to Lambda or Member Reference" is wrongly displayed for JDK 1.6 and JDK 1.7, etc.

Tested with both native NB and Maven projects.

A workaround is to disable such hints (globally or per-project), but it's not too comfortable.
Comment 1 Jiri Prox 2016-03-24 16:12:10 UTC 
Can you please share the project with this incorrect behavior and the messages.log file?
 I've tested it and it worked fine for me, in the common J2SE project.

What build do you use?

Example project, messages.log, project cfg. screenshots.

See the attached ZIP file with the example project.

I use the latest dev. build, JDK 1.8 as the default NB platform and JDK 1.6/1.7 as the project platform (see the screenshots and messages.log included additionally in the attached ZIP for more details).

The screenshots with examples of invalid hints are taken with JDK 1.6 platform/source format. I've deleted the NB profile before, so I have a fresh one. The only prerequisite is to enable the relevant (or simply all) Java hints.

As I little bit remember, hints not relevant for the selected project platform/source format started to appear probably sometimes when the support for Java 1.5 (and lower) platform was removed from NetBeans. But I'm not 100% sure with this information.
Comment 3 Svata Dedic 2016-05-17 11:31:33 UTC 
Individual hints should test the source level and bail out if source level of the inspected code is inappropriate. For simple cases I've added support to declare the minimum required source level for hint implementors and fixed inappropriately enabled hints.

Fixed in jet-main#3890c6763ec6
