Issue reported by [~syan]:

The two newly added tests fails.

Tests:

tools/jar/ExtractFilesTest.java
tools/jar/MultipleManifestTest.java

Test log snippet:

/tmp/tone/run/jtreg/jdk-repo/jdk/test/tools/jar/ExtractFilesTest.java:38: error: package org.junit.jupiter.api does not exist

Tests backported as part of JDK-8335912

The minimum jtreg version of jdk11u-dev is 7.3.1+1, the minimum jtreg version of jdk8u-dev seems to be 5.1. So these two tests can't backport from jdk11u-dev to jdk8u-dev directively. The org.junit.jupiter.api does not exist in jtreg5.1
