jnlp and javawebstart technologies depracated in jdk9 - alternatives?

I just inherited project that consists of a Java applet and some server communications, and with it found out that this technology is no longer supported by oracle. My first thought was to wrap it in a JNLP and javawebstart but since oracle also marked this as deprecated in jdk9 i cannot use it as i need a long term support solution. I want to try avoiding a complete re-write of the applet. Does anybody have any ideas on this? Are there other alternatives on the market? Thank you in advance.
