Avoid generating class files with `$$` in the class file name with `scalac` - scala

Question

I am using jpackage to try and package up a Scala GUI application. Unfortunately, the windows jpackage implementation parses $$ as escaping a single $. Thus all the file names below get converted from
NeutrinoConfigPane$$anon$1.class
NeutrinoConfigPane$$anon$2$$anonfun$$lessinit$greater$1.class
NeutrinoConfigPane$$anon$2.class
NeutrinoConfigPane$$anon$3.class
NeutrinoConfigPane$$anon$4.class
NeutrinoConfigPane$$anon$5.class
NeutrinoConfigPane$$anon$6.class
NeutrinoConfigPane$$anon$7.class
to
NeutrinoConfigPane$anon$1.class
NeutrinoConfigPane$anon$2$anonfun$lessinit$greater$1.class
NeutrinoConfigPane$anon$2.class
NeutrinoConfigPane$anon$3.class
NeutrinoConfigPane$anon$4.class
NeutrinoConfigPane$anon$5.class
NeutrinoConfigPane$anon$6.class
NeutrinoConfigPane$anon$7.class
and then cannot find the files. Is there any way to use a different separator than $$ with scalac? For more information on jpackage toolchain see this related bug in the wix toolset
Is there any way to generate different class file names that avoid $$ with scalac?
