Conversion of exe files to jar file format

As far as we know, several ways how exe to jar conversion might potentially work, one of them being a simple repack between self-extracting archive and Java archive (for whatever reason). Nevertheless, if the .exe file is just wrapped Java file, you can decompress it back with most Java tools. In case that the code is actually compiled then you would probably need some dedicated Java development tools and decompiler.
