Crash on fresh start

[mosemister]

Just created a new SpongeVanilla using version 59 (latest recommended) and it loaded fine, I put 1 plugin in and from there it can not start, get this error (does not show the error on version 116 which I initially tried)

`java.lang.IllegalArgumentException: null

any help would be appreciated.

Edit: oh forgot to mention, the plugin I put in is one that I am making so if its my plugin then please state and I will show you the launch code

@mosemister What version of Java are you using ?

(Also, post the entire stacktrace please.)

[mosemister]

Java 8 Update 181

here is full stacktrace: https://gist.github.com/mosemister/8bdd44af13b9343cf9d6a99b3f7ec84c

Just installed Java 8 update 171 and that also didnt work

It looks like something is weird with your plugin. Could you upload the plugin JAR somewhere?

@mosemister Since you don't seem to use a build system, could you share the actual built JAR file? I doubt it is specific to something in your code, it seems like something is weird with the actual compiled classes.

[mosemister]

I am using gradle just didnt upload the gradle files, just the code to the repository. Ill share the file anyway. https://drive.google.com/open?id=1bepcgxfjwuCM8r_vX7dn72crnkJ6BA_f

[mosemister]

just decompiled the jar, its saying null. Ill take a look at whats happening with the building of the jar. Thanks everyone
