unable to connect to remote server using VPN


I am trying to connect to remote server using VPN using user1

However, the server terminated the connection and  emitted below in the server log. 


[2018-04-14 13:13:33 #2 server]
java.lang.ClassCastException: java.base/[Ljava.lang.Object; cannot be cast to [[B

The users section in objectdb.conf in server is as follows.

                <user username="admin" password="admin" >
                        <dir path="/" permissions="access,modify,create,delete" />
                <user username="$default" password="$$$###" ip="">
                        <dir path="/$user/" permissions="access,modify,create,delete">
                                <quota directories="5" files="20" disk-space="5mb" />
                <user username="user1" password="user1" />


Thank you for this report. Please try build 2.7.4_06.
