It happens because there is a passwords mismatch into file:
jetty-ssl.xml
One of the solution would be to generate a password as explained here:
http://wiki.eclipse.org/Jetty/Howto/Secure_Passwords
and copy/paste this password to jetty-ssl.xml file :
<Configure id="sslContextFactory" class="org.eclipse.jetty.util.ssl.SslContextFactory">
<Set name="KeyStorePath"><Property name="jetty.base" default="." />/<Property name="jetty.keystore" default="etc/keystore"/></Set>
<Set name="KeyStorePassword"><Property name="jetty.keystore.password" default="OBF:paste_here_password"/></Set>
<Set name="KeyManagerPassword"><Property name="jetty.keymanager.password" default="OBF:paste_here_password"/></Set>
<Set name="TrustStorePath"><Property name="jetty.base" default="." />/<Property name="jetty.truststore" default="etc/keystore"/></Set>
<Set name="TrustStorePassword"><Property name="jetty.truststore.password" default="OBF:paste_here_password"/></Set>
NOTE:
1. On jetty 9 don't paste password in plain text it must be encrypted password generated by jetty utility. Here is an instruction how to get the password :
http://wiki.eclipse.org/Jetty/Howto/Secure_Passwords
2. To avoid confusions you can simply use the same password in all three instances into the file
jetty-ssl.xml for:
jetty.keystore.password
jetty.keymanager.password
jetty.truststore.password
