[jira] [Updated] (CASSANDRA-3970) JVM crash in streamingTransferTest on Windows

["Jonathan Ellis (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-3970?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Ellis updated CASSANDRA-3970:
--------------------------------------

    Attachment: hs_err_pid95744.log

The error log is always Unsafe.getByte in DirectByteBuffer in MappedFileDataInput, which seems to point to using a mmap'd buffer after it's unmapped.

Commenting out the "cleaner" unmapping in MmappedSegmentedFile makes the access violation crash go away, which supports this theory.  (It does cause the test to fail with EOFException later on, however.)
