Hi Jeroen,

We have problems with HTTPS connections from a docker installation. The
certificate can't validate. For validating the Java VM use the root
certificates saved in <java.home>\lib\security\cacerts. In IKVM this is
a virtual file. We receive different files if we read it directly inside
IKVM on different systems.

That the core Questions:

* From where read IKVM the cacerts file?
* Any idea how we can fix this?

Volker


How we have read the file:

File cert =3D new File(java.lang.System.getProperty("java.home") +
File.separator + "lib" + File.separator + "security" + File.separator +
"cacerts");

FileInputStream input =3D new FileInputStream(cert);

FileOutputStream output =3D new FileOutputStream("c:\\temp\\cert_export.t=
xt");

int data =3D input.read();

while(data !=3D -1)

{

   output.write(data);

   data =3D input.read();

}

input.close();

output.close();

=20

=20
