spring-boot-tools integration tests failing with Java 9

[snicoll]

This used to work so something recent must have introduced a regression.

This problem still in 2.0.0.M6

@netroby We have a JDK 9 build running on our CI server now and we've not seen the issue. This problem was specifically related to our build, so when you say "This problem still in 2.0.0.M6" do you mean you're trying to build M6 from a git tag, or something else?

I am using Spring Boot(v2.0.0.M7)

@roshangade this issue is closed and we don't use the tracker for questions, please ask them on StackOverflow. Having said that, this warning, as you can see, originates from spring-core, see this issue
