Debug InstanceTidier leak that only seems to appear when running in maven console #39

Open tolbertam opened 8 years ago

org.apache.cassandra.utils.concurrent.Ref$State@6b25a2cc) to class org.apache.cassandra.io.sstable.format.SSTableReader$InstanceTidier@1601791084:/Users/atolbert/Documents/Projects/sstable-tools/ma-1-big was not released before the reference was garbage collected.

Seems to happen for each SSTable opened, but only with mvn exec:java. I can't seem to reproduce using an executable jar.

Can reproduce it with executable jar too by attaching a yourkit agent. Must just be that there were no full GCs happening in my session.

The result of this is a file stays open per query/page until GC which is bad (such fix it).
