Cause
Currently, application links can exhibit some incorrect behavior when IPv6 is enabled due to the way Java deals with IPv6:
Resolution
Users can force Java to use IPv4 by adding by appending
-Djava.net.preferIPv4Stack=truetoJVM_REQUIRED_ARGSorJVM_SUPPORT_RECOMMENDED_ARGSin<Bitbucket Server installation directory>/bin/setenv.sh
setenv and environment variable changes in Bitbucket Server 5.0+
Starting with Bitbucket Server 5.0, setenv.sh and setenv.bat have been removed. The options that were set in this file can now be set via environment variables. Where to set the environment variable depends on which Operating System you're running on.
Linux
When using the atlbitbucket service on Linux, the environment variables are ignored. You must set the parameters in _start-webapp.sh (or start-bitbucket.sh). These values will be read when the service starts.
As an example, to set JVM_SUPPORT_RECOMMENDED_ARGS, you would add this line to the file:
JVM_SUPPORT_RECOMMENDED_ARGS=-XX:+HeapDumpOnOutOfMemoryError
Windows
Set the parameter as an environment variable for the user running Bitbucket Server. For example, if you want to set JVM_SUPPORT_RECOMMENDED_ARGS, create it as an environment variable and assign the appropriate value to it. When Bitbucket Server starts using the startup scripts or service, it will pick up and apply this value.
