INPUTsys Exe Packer creates executables with a Java Runtime Environment (JRE) and additional files embedded. When the packed application starts, the JRE files will be extracted to a temporary directory. The minimum size of the resulting executable file is 13MB. No ahead of time (AOT) compilation is done; the Hotspot compiler is used. There is a Java system property which points to the extracted directory, so your Java application can use whatever files have been packed into the executable.
