You should install Java 8 and configure the IDE to use it.

Do you have a link to old version B4J that runs OK on Java 7?

I have few customers that still run on Java 7 and don't want to update to Java 8 yet.

Note that you can install multiple versions of Java on the same computer (you don't really need to install anything, just copy the Java files).

Older versions of B4J are not available online.

My mistake, you can download v3.70 here: www.b4x.com/b4j/files/B4J_3.7.exe

This is the last version where the server library supported Java 7.

I have tried to install Java 8 on my PC, project compiled OK, but ran error on clients that still have Java 7.

So back to B4J ver 3.7, thanks for the link.

That is expected as Java 8 is required.

If possbile explain to your customers that Java is on version 8 due to many security updates, too. I had this situation but was in the position to force a company to use Java 8
