Do you have the test? Maybe you can try the latest version of hornetq.

I am using latest version 2.3.0

Hi,

Honestly after a first look in the code, from the looks of it, I think the bug is inside your code.

It seems that at

{code}com.gamescale.messaging.hornetQ.HornetQMessageConverter$.extractGSMessage(HornetQMessageConverter.scala:68){code}

, you are calling

{code}HornetQBuffer.readNullableString(){code}

in the wrong order perhaps?

Something along the lines of:

{code}writeInteger(-13);
writeNullableString("foo123");
{code}

then at your conversion code you are doing:

{code}// not reading the negative integer separately...
String foo = readNullableString();
{code}
