Subject: fdo#38913: Prevent invalid parameter handler crashes

It appears that on Windows at least some jvm.dll versions can cause calls to
_fileno(NULL), which leads to a call of the invalid parameter handler (see
<http://msdn.microsoft.com/en-us/library/ksazx244%28v=vs.80%29.aspx> "Parameter
Validation: Visual Studio 2005").  The default handler causes the application to
crash, so install a "harmless" one instead.
