Pl/Java broken since Postgresql 8.3-rc1

Hi,

I'm following the 8.3 beta releases for some time now, mostly using the
Win32 with Installer package.

8.3beta3 and 4 have worked perfectly with the provided pljava ddl, just
with 8.3-rc1 it doesn't work anymore.

i.e.

1. automatic installation of Pl/Java via Installer fails.
2. manual Installation via

CREATE FUNCTION java_call_handler() RETURNS language_handler
    AS 'pljava', 'java_call_handler'
    LANGUAGE c;

raises the following error:

ERROR:  could not load library
"C:/Programme/PostgreSQL/8.3-rc1/lib/pljava.dll": unknown error 127

Tested on two different WinXP machines with JDK 1.6.

Regards,

Jan Ischebeck
