David, that PTF only applies to native methods; I think you're
having trouble calling a method.  There was another PTF SI02011
to fix a problem where Java calls would fail if the CCSID of the
source file was 65535, but that would have caused all the message
replacements to be blank, not just the signature.  (It's one of
the superseding PTFs to the other one you found, so you probably
already got it.)

The best place to report manual problems is by clicking the
Feedback button in the Info Center.  It's the button that looks
like a stubby pencil, near the top right corner.

For what it's worth, your program worked ok for me after I
added some stuff (constructors) - here's my whole program:

H thread(*serialize)
DjavaString       c                   'java.lang.String'
DjavaBigDec       c                   'java.math.BigDecimal'
DnewString        PR              O   EXTPROC(*JAVA:javaString:
D                                       *constructor)
D   val                         50a   varying const
DnewBd            PR              O   EXTPROC(*JAVA:javaBigDec:
D                                       *constructor)
D   string                            like(newString) const
DbdAdd            PR                  LIKE(newBd)
D                                     EXTPROC(
D                                      *JAVA:javaBigDec:'add')
D BigDecimal                          LIKE(newBd)
DBd               s                   LIKE(newBd)
DBd2              s                   LIKE(newBd)
DString           s                   LIKE(newString)

C                   EVAL      String = newString ('10')
C                   EVAL      Bd = newBd (String)
C                   EVAL      Bd2 = bdAdd(bd : bd)
C                   seton                                        lr
