Update the google-java-format-gradle-plugin to the latest version and reformat the source files. Due to bug https://github.com/sherter/google-java-format-gradle-plugin/issues/25 the formatting was only checked on the :asm project, and not on the other subprojects. Version 0.7 of the plugin solves this issue.

Add an experimental suffix to the new features (also mark them deprecated and show a big warning in the Javadoc). Revert to ASM6 for the default api of the visitors, and use ASM7_EXPERIMENTAL only in tests (only exception: Trace*Visitor classes, which are final). This pattern could allow us to develop any new feature directly in 'master'.

Port the latest build file changes from master, and fix an issue with external dependencies depending on ASM.
