---------------------------------------
Summary: FST Sorter BufferSize causes int overflow if BufferSize >
2048MB
Key: LUCENE-4074
URL: https://issues.apache.org/jira/browse/LUCENE-4074
Project: Lucene - Java
Issue Type: Bug
Components: modules/spellchecker
Affects Versions: 3.6, 4.0
Reporter: Simon Willnauer
Fix For: 3.6.1, 4.1
the BufferSize constructor accepts size in MB as an integer and uses
multiplication to convert to bytes. While its checking the size in bytes to be
less than 2048 MB it does that after byte conversion. If you pass a value >
2047 to the ctor the value overflows since all constants and methods based on
MB expect 32 bit signed ints. This does not even result in an exception until
the BufferSize is actually passed to the sorter.
