Subject [jira] [Commented] (COMPRESS-382) OutOfMemoryError from CompressorStreamFactory
Date Mon, 24 Apr 2017 20:57:04 GMT

    [ https://issues.apache.org/jira/browse/COMPRESS-382?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15981908#comment-15981908
] 

Gary Gregory commented on COMPRESS-382:
---------------------------------------

I should add that over in Log4j-land, we have been migrating from ctors and factory methods
to builders and the overall code is much better. The main driver for us in Log4j was to avoid
binary compat issues and avoid the proliferation of more and more factory methods every time
a parameter needs to be added to a given class.

> While using Tika-1.14 to detect file types, the attached 1KB file triggered an OOME with
1GB heap. Tika calls CompressorStreamFactory.createCompressorInputStream(in) to detect if
the file is a compressor stream, but CompressorStreamFactory erroneously detects it as a LZMACompressorInputStream
and when the LZMACompressorInputStream is instanciated the OOME is thrown. This error does
not happen with commons-compress versions prior to 1.10, when auto detecting LZMA streams
was added. OOME stacktrace below:
