After modifying gnu/expr/Mangle.java and running 'make clean; make' it
seems to work properly. The d8 tool reports the folowing issues:

Stripped invalid locals information from 5 methods.
In libs/kawa.jar:gnu/kawa/slib/syntaxutils.class:
  Methods with invalid locals information:
 java.lang.Object
gnu.kawa.slib.syntaxutils.unrewriteQuote(gnu.expr.QuoteExp)
                                                          Type information
in locals-table is inconsistent. Cannot constrain type: BOTTOM (empty) for
value: v39(val) by constraint INT.                      In
libs/kawa.jar:kawa/lib/bytevectors.class:
  Methods with invalid locals information:
  java.lang.Object
kawa.lib.bytevectors.bytevectorAppend(gnu.lists.U8Vector[])
  Attempt to define local of type int as result:gnu.lists.U8Vector
 In libs/kawa.jar:kawa/lib/kawa/mstrings.class:
  Methods with invalid locals information:
 java.lang.CharSequence kawa.lib.kawa.mstrings.stringMap(java.lang.Object,
java.lang.CharSequence, java.lang.CharSequence[])
  Type information in locals-table is inconsistent. Cannot constrain type:
INT for value: v126 by constraint OBJECT.
In libs/kawa.jar:kawa/lib/numbers.class:
  Methods with invalid locals information:
  boolean kawa.lib.numbers.isInteger(java.lang.Object)
  Type information in locals-table is inconsistent. Cannot constrain type:
BOTTOM (empty) for value: v50 by constraint INT.
In libs/kawa.jar:kawa/lib/strings.class:
  Methods with invalid locals information:
  void kawa.lib.strings.stringForEach(java.lang.Object,
java.lang.CharSequence, java.lang.Object[])
  Type information in locals-table is inconsistent. Cannot constrain type:
INT for value: v164 by constraint OBJECT.
Some warnings are typically a sign of using an outdated Java toolchain. To
fix, recompile the source with an updated toolchain.


But other than that, the build finishes, and the example program runs
properly.

Thanks.
