Subject [jira] [Closed] (TIKA-1388) Tika IOUtils java.lang.OutOfMemoryError
Date Fri, 20 Mar 2015 21:28:38 GMT

     [ https://issues.apache.org/jira/browse/TIKA-1388?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tyler Palsulich closed TIKA-1388.
---------------------------------
    Resolution: Not a Problem

You can't convert an infinite [InputStream|https://github.com/tutmosisII/TDDJNTikaOutOfMemoryError/blob/master/src/test/java/co/edu/unbosque/test/IOUtilsOutOfMemoryErrorTest.java]
to a {{Byte[]}} with finite memory. So, I'm closing this as Not a Problem.

If someone thinks we should provide the capability to limit the number of bytes copied over,
please open a new issue.
