          Issue Type: Bug
          Components: Tika extractor
    Affects Versions: ManifoldCF 2.12

I have created an Issue with fontbox too: 

 

When using the internal Tika extractor in a Manifold Job on certain occasions I get an Out
of Memory Error.

{code}
I've allocated 8g of heap size, Installed the latest version of Tika (1.20) and PDFBOX (2.0.14).
But no solutions found.

After a heap dump and analyzing this dump, I notice that it is the Integer class that takes
about 2.6g of memory. 

Any suggestions?
