- Unify TKit.createTempDirectory() and TKit.createTempFile() functions. Remove `throws IOexception` from their signatures. Add relevant tests. - JPackageCommand.java: remove try/catch(IOexception) around `TKit.createTempDirectory()` call. - AppImagePackageTest.java: replace `TKit.createTempDirectory(null)` with `TKit.createTempDirectory("appimage")` to fix NPE. - Make `TKit.assertDirectoryExists(Path, Optional<Boolean>)` private. This is internal and shouldn't be exposed. - add `TKit.assertEquals(boolean, boolean)` and `TKit.assertNotEquals(boolean, boolean)` with tests. - AdditionalLauncher.java: remove redundant code duplicating functionality of `TKit.createTempFile()` (should have been cleaned long ago). - JPackageCommand.java: add a check for the main jar in the app image if the main jar was specified. Missing part of [JDK-8325089](https://bugs.openjdk.org/browse/JDK-8325089).
