             Summary: PSDParser creates unnecessary large byte array and discards it

                 URL: https://issues.apache.org/jira/browse/TIKA-2447
             Project: Tika
          Issue Type: Bug
          Components: parser
    Affects Versions: 1.16, 1.15
         Environment: openjdk version "1.8.0_131"
few memory (currently using 256M xmx)
            Reporter: Jan Burkhardt

PSD (Adobe Photoshop) are split into ResourceBlock's which contain different data, but only Caption Blocks are currently extracted into the description.
Parsing a file with very big blocks, i.e. for image data, a byte array of the size of the block is allocated:
https://github.com/justsocialapps/tika/blob/master/tika-parsers/src/main/java/org/apache/tika/parser/image/PSDParser.java#L191

even if it is discarded after that:
https://github.com/justsocialapps/tika/blob/master/tika-parsers/src/main/java/org/apache/tika/parser/image/PSDParser.java#L117 and following lines

I will prepare a pull request to fix that.
