I forgot to mention. It only occurs when I try to merge a decent number of documents (at least 10). Also, another IndexOutOfBoundsException occurs elsewhere, though it may be unrelated:

Caused by: java.lang.IndexOutOfBoundsException: Index: 145, Size: 145

This is occuring at: at ares.document.MergedPdfDocument.mergeDocuments(MergedPdfDocument.java:191) [classes:]

>                 Key: PDFBOX-2225
>                 URL: https://issues.apache.org/jira/browse/PDFBOX-2225
>             Project: PDFBox
>          Issue Type: Bug
>          Components: Utilities
>    Affects Versions: 1.8.6
>         Environment: Windows 7 64-bit, JDK8, pdfbox 1.8.1 or 1.8.6
>            Reporter: Brandon Lyon
>            Priority: Minor
>
> Edit: Problem confirmed to exist in 1.8.1 and 1.8.6
> The following exception will occur if any type of Exception other than IOException is thrown within a particular try-catch in PDFMergerUtility.appendDocument:
> java.lang.ClassCastException: java.lang.IndexOutOfBoundsException cannot be cast to java.io.IOException
> For the version I am using (1.8.1), the problem occurs on line 294
> The problem is that the author mistakenly assumed that the only exception which could be caught was IOException. I recommend that the cast be removed, and that either the additional checked exceptions be thrown by appendDocument or wrapped with an unchecked exception
> Also, anyone seeing this may want to investigate why an IndexOutOfBoundsException is occurring here, though this is obviously a separate issue
