This change addresses a bug with the "jar --create" operation, where if the original file name is lesser than 3 characters, the temporary file creation which uses the original file's name as the temporary file name prefix, runs into an exception. Although this issue is sort of an edge case (as in most cases the ".jar" extension will be used), there are scenarios where it may intentionally be omitted (ex: with Linux binfmt making Java programs look and feel like native Linux binaries). Ran GHA Sanity Checks, local Tier 1 and 2, and new test directly. Patch is clean.
