[jira] [Created] (LUCENE-6745) RAMInputStream.clone is not thread
safe
Michael McCandless created LUCENE-6745:
------------------------------------------
Summary: RAMInputStream.clone is not thread safe
Key: LUCENE-6745
URL: https://issues.apache.org/jira/browse/LUCENE-6745
Project: Lucene - Core
Issue Type: Bug
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: Trunk, 5.4
This took some time to track down ... it's the root cause of the RangeTree failures that [~steve_rowe] found at https://issues.apache.org/jira/browse/LUCENE-6697?focusedCommentId=14696999&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14696999
The problem happens when one thread is using the original IndexInput (RAMInputStream) from a RAMDirectory, but other threads are also cloning that IndexInput at the same time.
