Oracle forms - webutil register function problem with java 8

Hi,

We are using Oracle Forms 11.1.2.2 with weblogic 10.3.6.

I made a dll that is used in oracle forms to connect to a bankterminal to pay something with a creditcard.

Everything works fine with java 7 for several months

I configured webutil.cfg so that the dll is downloaded in the jre\bin directory.

For java 7 and for java 8 client the dll is downloaded correctly.

But on the java 8 client he gives an exception an the next statement.

"f_handle := WEBUTIL_C_API.register_function('vicemv_dgmv.dll','SetComPortDgmv');"

He keeps telling that the dll is not accessible and give a WUL-928 error.
