Performance improvements, HA improvements
<ul>
<li>Set higher timeout for the access of the partner management - this allows to reach the partner settings even if the system is under high load</li>
<li>Database migration dialog: The database files have been loaded from the client side but needed to be loaded from the server side</li>
<li>Added synchronization between the file streams and the underlaying file system provider. If multiple nodes access the same files it is required they are physical written to the file system</li>
<li>Timing problem in the HA overview dialog: Some nodes were shown as offline even if they are already in the cluster</li>
<li>Added connection pooling for the underlaying database connections (PostgreSQL, HSQLDB): (Hikari CP)</li>
<li>The HA overview dialog now shows the public IP and the instance id if run on AWS</li>
<li>Updated BouncyCastle to v169 (crypto API)</li>
<li>Update MINA to 2.1.4 (async io framework for client-server architecture)</li>
</ul>
