Did we actually hit null pointer issue in some specific condition using ImageIO or this bug got identified because of some static analysis?

Did we actually hit null pointer issue in some specific condition using ImageIO or this bug got identified because of some static analysis?

I just grepped the codebase for GetPrimitiveArrayCritical usages and while doing so saw this.

jayathirthrao · 2022-11-23T12:16:54Z

Thanks for the fix. Change looks good to me.
I am running ImageIO tests with fix and will approve soon. There should not be any issues.

Should I open another jbs issue for them ?

kiraka42 · 2022-11-23T14:33:49Z

some tests are failing

MBaesken · 2022-11-23T14:37:18Z

Yes some Windows tests are failing; however it seems they miss getting the BOOT JDK or other components for example
https://github.com/MBaesken/jdk/actions/runs/3530303514/jobs/5923400590

so this looks not related to me.
