     [ https://issues.apache.org/jira/browse/PDFBOX-2538?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andreas Lehmkühler closed PDFBOX-2538.
--------------------------------------
    Fix Version/s: 3.0.0 PDFBox
                   2.0.2
       Resolution: Fixed

The described exception no longer occurs starting with 2.0.2. I didn't dig deeper into this to find the change fixing this.

> e.g. error 4 in PDFBOX-2513
> after all, we know what the reason is.
> Ideas:
> 1) create COSStreamException extends IOException in COSStream.java
> 2) in SinglePageValidationProcess.validateContent() examine the root cause exception type to classify smarter than just ERROR_UNKOWN_ERROR
> any other thoughts?
