OutOfMemoryError while loading metadata of a jpeg image
-------------------------------------------------------

                 Key: SANSELAN-3
                 URL: https://issues.apache.org/jira/browse/SANSELAN-3
             Project: Sanselan
          Issue Type: Bug
            Reporter: Philippe Gassmann
            Assignee: Carsten Ziegeler
            Priority: Blocker
         Attachments: 2127422194_4734e30dcb_o.jpg

the code executed : 

IImageMetadata metadata = Sanselan.getMetadata(new File(sourcePath));

the stacktrace : 

java.lang.OutOfMemoryError: Java heap space
at org.cmc.sanselan.common.byteSources.ByteSourceArray.getBlock(ByteSourceArray.java:51)
at org.cmc.sanselan.formats.tiff.TiffField.fillInValue(TiffField.java:356)
at org.cmc.sanselan.formats.tiff.TiffReader.readDirectory(TiffReader.java:164)
at org.cmc.sanselan.formats.tiff.TiffReader.readDirectory(TiffReader.java:105)
at org.cmc.sanselan.formats.tiff.TiffReader.readDirectories(TiffReader.java:96)
at org.cmc.sanselan.formats.tiff.TiffReader.read(TiffReader.java:416)
at org.cmc.sanselan.formats.tiff.TiffReader.readContents(TiffReader.java:406)
at org.cmc.sanselan.formats.tiff.TiffImageParser.getMetadata(TiffImageParser.java:127)

In the method fillInValue, the method getBlock is called with a length of more than 1,300,000,000
thus resulting in an OOME (the method tries to allocate a byte array of more than 1.3 gigabytes)

I will attach the guilty picture that triggers this issue
