      Description

      A DESCRIPTION OF THE PROBLEM :
      The JNICALL (__stdcall) declarations added to the splash screen native source in response to bug #8201226 cause the splash screen function names to be decorated in 32-bit Windows. This way they can't be loaded anymore with GetProcAddress and their simple names (that they still have in 64-bit Windows, because __stdcall is ignored there).

      REGRESSION : Last worked in version 8u202

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Call "dumpbin splashscreen.dll /EXPORTS"

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Should show
      [...]
               11 0 0001C86A SplashClose
               12 1 0001D863 SplashGetScaledImageName
      [...]
      etc
      ACTUAL -
      Shows
      [...]
               11 A 0001C868 _SplashClose@0
               12 B 0001D86B _SplashGetScaledImageName@20
      [...]
      etc

      CUSTOMER SUBMITTED WORKAROUND :
      Patch the source files, removing the JNICALL declarations in splashscreen_impl.h, splashscreen_impl.c and splashscreen_sys.c before building the JDK.

      FREQUENCY : always
