Thanks for bringing this up as a few people have reported issues with 
Maven not finding the compiler.

Just to be clear, are you seeing this issue with the regular JDK 9 EA 
builds or just the Jigsaw EA builds? Did this start when tools.jar went 
away? I just did a quick test to check that 
ToolProvider.getSystemJavaCompiler() is returning the system 
JavaCompiler is returned for both builds (and it is). Is the issue that 
you are seeing that getSystemJavaCompiler() is returning null?
