Description

There's a problem with google-java-format Intellij plugin version 1.7.0.5 that causes an UnsupportedOperationException when creating a new Java class file. Besides the exception, an error dialog pops up and the newly created file is not properly formatted. A simple reformat solves the issue.

This problem is caused by a bug that got fixed in the google-java-format plugin's codebase in 45fb41a.

Unfortunately, this fix got released with the plugin version 1.8.0.1 which we cannot upgrade to due to our limitations on sticking to Java 8 for now (see FLINK-20803).
