I already have a patch for this particular item, but haven't sent it out 
for review yet (the change grew a bit). In general, when an item is 
assigned to someone in JIRA, it usually means that that person is 
working on it. It could also be good to know that GC enhancements (as 
opposed to bugs) always have fix version set to "tbd" until they are 
pushed, so "tbd" is not an indication that no one it working on it.

If you're looking for starter bugs/enhancements to fix, you can look for 
the "starter" label in JIRA. Those are usually a good place to start for 
people that are new to the code base.

For example: 
https://bugs.openjdk.java.net/issues/?jql=project%20%3D%20jdk%20and%20component%20%3D%20hotspot%20and%20status%20in%20(new%2C%20open)%20and%20labels%20in%20(starter)

cheers,
Per
