After configuring and compiling the latest zabbix_server 1.9.8 beta with:

./configure --prefix=/opt/local --enable-server --enable-java --with-mysql --with-jabber --with-libcurl --with-net-snmp --with-ssh2=/usr/local --with-ldap --with-openipmi
make install

When trying to start the zabbix_server daemon I get this error:

Starting zabbix_server1.9: zabbix_server1.9 [6325]: unknown parameter [JavaProxyPort] in config file [/opt/local/etc/zabbix/zabbix_server.conf], line 200

The 'JavaProxyPort' line worked perfectly fine in the 1.9.7 beta release. After commenting the line out, the daemon starts fine but we want to be using and testing the JMX monitoring capabilities.

Let me know if there is any other info that might be helpful to you.
