OutOfMemory when extracting text from pdf
-----------------------------------------
Key: PDFBOX-778
URL: https://issues.apache.org/jira/browse/PDFBOX-778
Project: PDFBox
Issue Type: Bug
Environment: Mac OS X
Reporter: Mario Sangiorgio
I have to extract text from hundreds of documents, but at a certain point I get
an out of memory exception.
It seems that the memory leak is related to a single file that I attached.
Please let me know if you need more details.
This is the stacktrace of the exception:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
