Leaking buffer negative index fault #241
Description
I found that when my source is "slow", buffer grows infinitely till it throws java.lang.NegativeArraySizeException. Spent quite some time trying to find minimal reproducible example (it was failing on my 8GB json I didnt really want to post here :D).
@Test
public void leakTest() throws IOException {
InputStream slowStream = new InputStream() {
int position = 0;
boolean pretendEmptyNextRead = false;
byte[] src = "{\"a\":\"123456789abcdef\"}".getBytes();
@Override
public int read() throws IOException {
if (position < src.length) {
if (pretendEmptyNextRead) {
pretendEmptyNextRead = false;
return -1;
} else {
pretendEmptyNextRead = true;
return src[position++];
}
}
return -1;
}
};
JsonIterator jsonIterator = JsonIterator.parse(slowStream, 1024 * 1024);
jsonIterator.readObject();
jsonIterator.readAny();
}If you run this you will get the exception before parsing whole string. If I observe byte[] newBuf = new byte[iter.buf.length * 2]; it growths even if it doesnt need to.
This issue is probably duplicate of this #124. Using version 0.9.19.
