Error while processing

Hi there,

I was trying ahead of time instrumentation for Apache tika, but it threw a lot of errors at me:

Output files are available at /opt/java-afl/instrumented
Instrumented 0 .class files and 1 .jar files with 1120718 locations.

Are these fatal errors? Did the instrumentation work at all? Are these just warnings?

[Barro]

They are technically warnings. This is a limitation with the libraries that this tool depends on.

[floyd-fuh]

Ok. Can we turn these into warnings then?

But I doubt they are warnings. Because afterwards when I try to fuzz, it won't find org/apache/tika/exception/TikaException or no instrumentation is detected:

Can we fix this? Did you try running Tika with java-afl?
