> you could try building the jar using #3090 but if gc() isn't running I fail to see how using Cleaner will work

@davecramer I built the snapshot with #3090 and tried but I get same thing :/ GC is definitely running but I can see that it frees up about ~15MB of Metaspace but thats not enough (when close the limit) and the OOM is thrown. 
@vlsi  the queue seems to be empty on all instances I checked.
