Troubleshooting General Help

Hello,
I just switched to JDK 1.8.0_212 (from 1.7.0_80) and I’m getting this error:

When working with JDK 7 everything runs fine but I cannot use Stephen Gold’s Mine library…
I have seen threads speaking about Nvidia driver downgrade for solving this issue but I have Intel driver and it works fine with JDK 7 so I wonder if anyone has encountered such issue with JDK 8 and what was the resolution?
Alternatively can Mine run with JDK 7?

Thanks
Adi

Have you tried updating your intel driver? Usually the default windows driver is the issue, and you need the actual vendor driver (e.g. if you have a HP laptop, get the drivers from the HP website).

Yes, the driver is up to date but it is not from HP (I have a HP laptop). It works fine with JDK 7 though… so it’s something with JDK 8 that is making the difference. Stephen said he will compile Minie against JDK 7 so I hope to migrate to Minie in the near future

Actually, you use a more recent version of Java that is “Windows 10 aware” and your driver just crashes in this case. Then, the slow driver using Microsoft GDI renderer is used. It’s a known problem. I advise you to look for a workaround in the list of issues on the Github repository of LWJGL. This should help:
