getSystemJavaCompiler returns null with jbr17

[idanakav]

What happened?

When applying the plugin it will also enforce JBR as the JDK, with JBR17, the getSystemJavaCompiler is returned null, most likely due to classpath modifications.

This is causing issues for some tools, such as compile-testing when tried to be used in the same project.
