Shalin Shekhar Mangar created SOLR-7983:
-------------------------------------------
Summary: Utils.toUTF8 uses shorter buffer than necessary for
holding UTF8 data
Key: SOLR-7983
URL: https://issues.apache.org/jira/browse/SOLR-7983
Project: Solr
Issue Type: Bug
Affects Versions: 5.3
Reporter: Shalin Shekhar Mangar
Priority: Trivial
Fix For: Trunk, 5.4
Method in question:
{code}
public static byte[] toUTF8(CharArr out) {
byte[] arr = new byte[out.size() << 2]; // is 4x the real worst-case
upper-bound?
int nBytes = ByteUtils.UTF16toUTF8(out, 0, out.size(), arr, 0);
return Arrays.copyOf(arr, nBytes);
}
{code}
The byte array should be at least out.size() * 3.
