Desired Behavior:
Even when using a codedir with only the inifile module installed, it should work.

In this example, /tmp/configure_inifile.aPkO3n is a tmpdir with just the inifile module installed.

An inifile resource such as the following should modify the existing java_args line:
 

[root@b3wa4ws5mg41efr ~]# puppet apply --codedir /tmp/configure_inifile.aPkO3n -e 'ini_setting { "JAVA_ARGS":

 ensure => present,

 path => "/etc/sysconfig/puppetserver",

 section => "",

 setting => "JAVA_ARGS",

 key_val_separator => "=",

 value => "\"-Xmx2g -Xms2g -XX:+PrintTenuringDistribution -XX:+PrintGCDateStamps -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Xloggc:/var/log/puppetlabs/puppetserver/gc.log\"",

}'

In this case the value of JAVA_ARGS in the file is JAVA_ARGS="-Xms2g -Xmx2g -Djruby.logger.class=com.puppetlabs.jruby_utils.jruby.Slf4jLogger"

Actual Behavior:

It does not. inifile seems to be able to remove lines and add lines that don't already exist, but modifying existing lines does not work. Unfortunately even with --trace, --verbose and --debug there isn't anything useful coming out of the module. Note: this seems to only be the case when inifile is installed in its own codedir and puppet apply --codedir $codedir is used. When inifile is present in /etc/puppetlabs/code/environments/production/modules/inifile with other modules the resource behaves as expected.
