Description

to reproduce this command could be used (assuming that something like ./mvnw clean verify -DskipTests -Dfast was run before)

cd flink-runtime && ./../mvnw -Dtest=FsMergingCheckpointStorageLocationTest test && git status

the output will contain something like

Untracked files:
  (use "git add <file>..." to include in what will be committed)
	org.junit.rules.TemporaryFolder@3cc1435c/
	org.junit.rules.TemporaryFolder@625732/
	org.junit.rules.TemporaryFolder@bef2d72/

the reason is that in @Before there not absolute path is in use
