Tracing it down, I find that IntegerType's getString method() looks like this:
{code:title=IntegerType.java|borderStyle=solid}
public String getString(ByteBuffer bytes)
{
if (bytes == null)
return "null";
if (bytes.remaining() == 0)
return "empty";
return new
java.math.BigInteger(TBaseHelper.byteBufferToByteArray(bytes)).toString(10);
}
{code}
TBaseHelper.byteBufferToByteArray() looks like this:
{code:title=TBaseHelper.java|borderStyle=solid}
public static byte[] byteBufferToByteArray(ByteBuffer byteBuffer) {
if (wrapsFullArray(byteBuffer)) {
return byteBuffer.array();
}
byte[] target = new byte[byteBuffer.remaining()];
byteBufferToByteArray(byteBuffer, target, 0);
return target;
}
public static boolean wrapsFullArray(ByteBuffer byteBuffer) {
return byteBuffer.hasArray()
&& byteBuffer.position() == 0
&& byteBuffer.arrayOffset() == 0
&& byteBuffer.remaining() == byteBuffer.capacity();
}
public static int byteBufferToByteArray(ByteBuffer byteBuffer, byte[] target,
int offset) {
int remaining = byteBuffer.remaining();
System.arraycopy(byteBuffer.array(),
byteBuffer.arrayOffset() + byteBuffer.position(),
target,
offset,
remaining);
return remaining;
}
{code}
The second overloaded implementation of byteBufferToByteArray is calling the
bytebuffer's array() method.
Suggested fixes:
1) Don't use TBaseHelper in IntegerType.getString(), use
ByteBufferUtil.getArray()
2) Report problem upstream to Thrift.
3) Find a better way to deserialize BigIntegers that doesn't require an array
copy.
