spotless-maven-palantirJavaFormat : last character not a \n -> check fails

[bodote]

Problem: using palantirJavaFormat with spotless maven : last character not a \n -> check fails

when creating a new java class using Intellij with palantir-java-format for formating all java files
AND using spotless with palantirJavaFormat
AND
the last line in a java file is not an empty line but just } with no \n appended
THEN
the spotless:check fails

what i would expect instead

I would expect that the check should pass no matter of the \n as the last character in java files, just as the palantir-java-plugin for intellij does not care.

EDIT: and/or I expect that the Intellij palantir-java-plugin adds a \n to the end of each java file all by itself.

Details:

• Maven version 3.8.6
• spotless version com.diffplug.spotless:spotless-maven-plugin:2.41.1
• operating system and version windows 10
• Intellij - palantir-java-plugin version 2.39.0
