Ipscan jdk errors

I have added ipscan but when I run it I get open jdk errors.
Has anyone got ipscan to run.
I have an error log but don’t know how to attach it.
This is the beginning of the error log
***WARNING: GTK+ version too new (major mismatch)
***WARNING: SWT requires GTK 2.18.0
***WARNING: Detected: 2.24.32
