Is there any limitation on the inital capacity of

The following line of code fails with the below-mentioned exceptoin:
int capacity = 2147480000;
org.apache.mina.common.ByteBuffer byteBuffer =
org.apache.mina.common.ByteBuffer.allocate(capacity);
Exception in thread "main" java.lang.IllegalArgumentException: Buffer size

while the same request using NIO ByteBuffer succeeds:
"java.nio.ByteBuffer byteBuffer = java.nio.ByteBuffer.allocate
(capacity);"
This test was done on a Windows Enterprise 2003 64-bit, MINA Version 1.0.1

JDK 5.0
The default buffer allocator pools the buffer, so we thought pooling too big
buffer won't make sense. If you want to create a bigger buffer, please
change the allocator:
ByteBuffer.setAllocator(new SimpleByteBufferAllocator());
