Description
Currently, Bitbucket is bundled with SSHD 2.4.1 which does not allow for a minimum DH size.
This property is available in 2.6+ of the package and would allow for the org.apache.sshd.minDHGexKeySize property to be set by adding the following to the JVM_SUPPORT_RECOMMENDED_ARGS:
-Dorg.apache.sshd.minDHGexKeySize=2048
