A DESCRIPTION OF THE PROBLEM :
If CharsetDecoder.decode(ByteBuffer) is called on a ByteBuffer with size close to Integer.MAX_VALUE, IllegalArgumentException is thrown due to integer overflow in output buffer size allocation.

In most cases (characters per byte 1.0 or less), decode() should handle up to Integer.MAX_VALUE sized ByteBuffers. In cases where characters per byte can be greater than one and output size would exceed Integer.MAX_VALUE, then perhaps some new subclass of CharacterCodingException, such as "OutputSizeException" could be thrown.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run as:
   java -Xms8G -Xmx8G CharsetDecoderBug


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No output.
ACTUAL -
Exception in thread "main" java.lang.IllegalArgumentException: capacity < 0: (-2000127 < 0)
at java.base/java.nio.Buffer.createCapacityException(Buffer.java:278)
at java.base/java.nio.CharBuffer.allocate(CharBuffer.java:360)
at java.base/java.nio.charset.CharsetDecoder.decode(CharsetDecoder.java:814)
at CharsetDecoderBug.main(CharsetDecoderBug.java:14)


---------- BEGIN SOURCE ----------
import java.nio.charset.*;
import java.nio.*;

public class CharsetDecoderBug {
   public static void main(String[] args) {
      Charset charset = Charset.forName("utf8");
      CharsetDecoder decoder = charset.newDecoder();
      // This works. // int size = Integer.MAX_VALUE - 10000000;
      int size = Integer.MAX_VALUE - 1000000;
      byte[] bytes = new byte[size];
      ByteBuffer bb = ByteBuffer.wrap(bytes, 0, size);
      try {
         decoder.decode(bb);
      }
      catch (CharacterCodingException ignored) {
      }
   }
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Enforce a lower limit on the size of the ByteBuffer before calling decode().

FREQUENCY : always
