NoClassDefFoundError: JavacProcessingEnvironment at runtime after updating tomcat 8

Question

After updating the project to spring boot 1.5.9 (spring 4.3 and tomcat 8.5.24), the service using queryDSL does not work at run time because it cannot find the class from jdk lib (tools.jar).

It works when I add tools.jar as a gradle dependency, but this is not a solution because jdk libraries should not be packaged into a project.

compile files(org.gradle.internal.jvm.Jvm.current().toolsJar)

We are on the old version of queryDSL (2.7.3), and the project has generated code linked to the repo (this is an old project, which I would rather generate when compiling).

Update: After switching to tomcat back to v7.0. * It will start working again.

Any idea what has changed in tomcat 8? It looks like this is not loading jdk libs.
