Thanks a lot for checking this out.
We're using Equinox as well. We're on an older version though, so I wonder if
that has something to do with this (osgi-3.5.2.R35x_v20100126.jar). We
have some other issues that prevent us from upgrading for now.
I was actually able to get past the gem loading issue by manually setting
GEM_PATH to the appropriate path (ugly, but I wanted to see if it would work):
scriptingContainer.runScriptlet("ENV['GEM_PATH']='/opt/raritan/polaris/lib/configuration/org.eclipse.osgi/bundles/3/1/.cp/META-INF/jruby.home/lib/ruby/gems/shared'");
However, then the code blew up with a NoClassDefFoundError for a Java class
that is in my OSGi bundle. In my case it just looks like when using CONCURRENT
the JRuby code is not playing nice with OSGi. Here are the relevant log
messages showing the ruby load path and Gem path as well the error message.

The OSGi Activator.start() method for the for the
com.raritan.polaris.plugins.dynamic-4.1.0-6-SNAPSHOT.jar bundle looks like:
public void start(BundleContext context) throws Exception
{
// Using OSGiScriptingContainer instead of vanilla ScriptingContainer now

scriptingContainer = new
OSGiScriptingContainer(context.getBundle(),LocalContextScope.CONCURRENT,
LocalVariableBehavior.TRANSIENT);
scriptingContainer.setCompatVersion(CompatVersion.RUBY1_9);
// Work-around JRUBY issue JRUBY-6265
scriptingContainer.runScriptlet("$: <<

// Let's try to manually set hard-coded GEM_PATH

// Initialize SNMP4J

BridgeUtils.setSnmpSession(snmpSessionManager.getSnmpSession());
@SuppressWarnings("rawtypes") Hashtable properties = new Hashtable();
context.registerService(CommandProvider.class.getName(), this, properties);
}
Not sure what I'm doing wrong. I tried to create a simple jUnit test that
reproduces this issue but so far no luck.
