I have small pdf file (142kb) while I'm trying to parse it with TIKA my
entire app is crashing on OOM with heap dump on 36gb (nothing else in the
code, hust parsing this PDF).
With possible error : FlateFilter: stop reading corrupt stream due to a
DataFormatException
And stack trace (at the moment of OOM):
"main" #1 prio=5 os_prio=0 tid=0x00007f6460009000 nid=0x4876 waiting for
monitor entry [0x00007f646680d000]

Please advise how can I detect that this can happen and skip such file from
the parsing. Or this is a bug ?
Thanks
