v->{var s="v->{var s=%c%s%1$c;System.console().printf(s,'}'-'[',s);}";System.console().printf(s,'}'-'[',s);}

System.console() will return null when none is provided, so TIO returns a NullPointerException in this case.

To prove it's a working quine, replace System.console() with System.out: Try it online.

v->{ // Method with empty unused parameter and no return-type
 var s="v->{var s=%c%s%1$c;System.console().printf(s,'}'-'[',s);}";
 // Unformatted source code
 System.console().printf(s,'}'-'[',s);}
 // Print formatted quine

Since the only way to have two quines in Java is using the unicode version with \uHEXA, which is converted to characters during compilation, I'm unable to use the characters 0123456789ABCDEF\u in the non-unicode version. So, the smaller non-unicode version will use System.console() instead of return or System.out (both containing a 'u'), and will use '}'-'[' instead of 34.

So, the smaller non-unicode version will use System.console() instead of return or System.out (both containing a 'u'), and will use '}'-'[' and two times %c instead of 34 and %1$c.
