Intention "create test" only works for Groovy classes

My main use case is to write Spock tests for Java classes. Other users might want to test Kotlin or other types of JVM classes. However, Shift-Strg-T for creating a new test for the current class only lists Spock when in a Groovy class. In Java, only the templates for JUnit 3-5 and TestNG appear. This should be fixed, even though the template is not so super helpful to me, but it might be for newbies.
