IllegalArgumentException thrown byElementEntry.encodeInit

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

This was UPAJ bug and it has been fixed. The fixed API is ETA(Elektron Transport API) Java version 3.0.0. UPA Java has been renamed to be ETA Java. ETA Java 3.0.0 is functionally equivalent to the UPA Java 8.0.0.L1.ETA Java 3.0.0 can be found in 2 packages

1.Elektron SDK - Java - 1.0.2: This SDK is an all encompassing package of all Elektron APIs. It includes the entire ETA Java distribution package and the Elektron Message API (EMA)

2. ETA - Java - 3.0.0 - All: The binary package that contains only the core, non-open source JAR and JNI files of ETA Java.

Both packages can be found at

After login , click on Elektron SDK - Java Edition .Next click Downloads.
