Netbeans 8.2 with jdk 9

Question

I have an issue on hdpi with netbeans, the icon become too small when I open it. Then I found the issue below. And someone says that jdk9 fix the resolution problem.

https://netbeans.org/bugzilla/show_bug.cgi?id=252452

Here is my environment:

• OS: windows 10 (64bit)
• JDK: JDK9 BUILD149
• netbeans 8.2

I downloaded jdk9 & netbeans8.2 on windows10, hoping that JDK9 might fix the annoying resoution issue. Unfortunately, I can't open the netbeans.

After I type this in cmd. netbeans.exe --jdkhome "C:\Program Files\Java\jdk-9" console show the error.

No way to find original stream handler for jar protocol

Does anyone know how to use jdk9 with Netbeans ?

As you noted yourself in a comment you need to use one of the nightly builds to get JDK 9 support. The full instructions are available here: http://wiki.netbeans.org/JDK9Support
