Luc Vanlerberghe created LUCENE-6409:
----------------------------------------
Summary: LongBitSet.ensureCapacity overflows on numBits >
Integer.MaxValue
Key: LUCENE-6409
URL: https://issues.apache.org/jira/browse/LUCENE-6409
Project: Lucene - Core
Issue Type: Bug
Components: core/other
Reporter: Luc Vanlerberghe
LongBitSet.ensureCapacity calculates the number of longs required to store the
number of bits correctly and allocates a long[] accordingly, but then shifts
the array length (which is an int!) left by 6 bits. The int should be cast to
long *before* performing the shift.
