<p>Hi Jeroen,<o:p></o:p></p>
<p>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.<o:p></o:p></p>
<div>
<p class="MsoNormal">That the core Questions: <br>
<br>
* From where read IKVM the cacerts file?<br>
* Any idea how we can fix this?<br>
