Tim Allison commented on COMPRESS-382:
--------------------------------------

My other thought on this...do we want to set the memory limit via some high level static variable?  With only a quick look through the code base, there appear to be quite a few places where the code relies on reading an {{int}} or a {{uint}} and then creating a {{new byte[uint]}}.  

If we go with a high-level static variable, we wouldn't have to add a second parameter constructor for every stream that requires this.  We'd still have to implement it throughout, and I'm happy to help, but we wouldn't have to add new ctors throughout.

> 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:
