What it does / What it does not do

  • What it does: works like a jar converter; can extract files with the jar file open (jar open) operation or package the jar as a single file into 7Z.
  • What it does not do: does not guarantee running “java -jar” from the content converted to 7Z (executable jar behavior is related to jar + manifest logic).
