What version of the product are you using? On what operating system?

persevere1.0.1.rc2.tar.gz on Windows.

Please provide any additional information below.

All identifiers are replaced with "xxxx" because it doesn't seem to make a
difference when I choose other names.

In my application I experienced the error too, with additional output of
persevere

First restart: 

SEVERE: Error occurred during indexing, the index may need to be rebuilt
java.lang.OutOfMemoryError: Java heap space

Second restart:
