ClassCastException from String to Long #554

Open Shepard opened 2 years ago

Shepard commented 2 years ago

I get a very similar exception to the recently reported issue #553.

The image I'm trying to read can be found here: https://tool.trendexplorer.com/uploads/microtrends/f/f/37973b9f1867abf32b5983899cf9cb8b7f4e9891.jpg Unfortunately I don't know what the licensing situation with this image is so I cannot provide it as a sample image for your public library.

In my case I'm using a wrapped version of 2.15.0.1 (org.tallison) as provided with tika-parsers but I could also reproduce this by feeding the image into ImageMetadataReader via the command line in version 2.16.0.

The exception there is:

java.lang.ClassCastException: class java.lang.String cannot be cast to class java.lang.Long (java.lang.String and java.lang.Long are in module java.base of loader 'bootstrap')

The offending line is:

directory.setLong(AppleRunTimeMakernoteDirectory.CMTimeValue, (Long)values.get("value"));

It seems it finds a String stored under the key "value".
