existing test (test/tools/launcher/modules/patch/basic/PatchTest.java) tests 2 scenarios:
1. testWithExplodedPatches, for example, patches1/java.base:patches2/java.base
2. testWitJarPatches, for example, patches/java.base-1.jar:patches/java-base-2.jar

there should be one more scenario to test mixture of both Jar and exploded patches.
