I have an issue encoding an element list.

I have a test whereby I have a message buffer 1024 bytes, the message contains an eleement list, containing a string element followed by an element containing a vector. The test is to encode refresh messages increasing the string element by one byte. ElementEntry.encodeInit throws an illegalArgumentException. This is because it is calling ByteBuffer.position(1025).

I expect to get a BUFFER_TOO_SMALL response after which I can encodeComplete(false) the elemententry, encodeComplete(true) the ElementList and Message and write the buffer.

Error occurs on UPA 7.4 and 8. I have enclosed the stack trace for 8

Data from breakpoint on IllegalArgumentException

params to HeapByteBuffer

this HeapByteBuffer (id=153)
arg0 1025
