[jira] [Updated] (LUCENE-5462) Lucene3xFields shouldn't use
RamUsageEstimator to estimate size
[ https://issues.apache.org/jira/browse/LUCENE-5462?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Adrien Grand updated LUCENE-5462:
---------------------------------
Attachment: LUCENE-5462.patch
Here is a patch that removes calls to {{RamUsageEstimator.sizeOf(Object)}} in Lucene 3.x terms, norms, term vectors and stored fields. So I think that there is no format producer anymore that relies on this method.
