Jan Høydahl commented on LUCENE-4074:
-------------------------------------
Checked in a fix in 3.6 for non-compiling TestSort.testRamBuffer. It referred
to random().nextInt() instead of random.nextInt() - clear copy/paste error from
Trunk code
> FST Sorter BufferSize causes int overflow if BufferSize > 2048MB

> 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.
