When I try to run ireport_w.exe from the command window, I get:

The current path is: C: \ Java \ jdk1.8.0

Java HotSpot (TM) 64-Bit Server VM warning: ignoring option MaxPermSize = 512m; support was removed in 8.0.

What should I do to run iReport Designer with JDK 8?

In general you may ignore this warning at least until Java-9. It warns you that this option became useless and may lead to the error in newer Java versions. In Java-8 PermGen was replaced with Metaspace which is more flexible in terms of memory usage, so you rarely need to tune its size explicitly.

If you still aware, you can find ireportpro.conf file in the iReport installation folder and remove -J-XX:MaxPermSize=512m part. The warning should disappear after that.
