AlternativeJREPanel deprecated - throws IllegalArgumentException in Idea version 15

Hi,

I'm looking into fixing the SBT plugin for intellij 15. The problems seems to be that the AlternativeJREPanel no longer works. Specifically I see this stacktrace:

Exception in thread "main" java.lang.IllegalArgumentException: Argument for @NotNull parameter 'componentManager' of com/intellij/openapi/components/ServiceManager.doGetService must not be null

I note that this class is deprecated but I couldn't find anywhere which I should use instead.

What's the best way to tackle this? Is there an alternative component - or would I need to write one from scratch?

Thanks,
Sam
