Cause

Bitbucket Server is using OpenJDK.

Resolution

Either register installed fonts in the Java font properties and continue using OpenJDK or set JAVA_HOME to a currently Oracle Supported version.

In order to run Bitbucket Server with OpenJDK:

1.  To run a java command to register installed fonts in the java font properties and continue using Open JDK:
   
   
   cd /usr/lib/jvm/java-6-openjdk-common/jre/lib
   sudo java -jar compilefontconfig.jar fontconfig.config fontconfig.bfc
    
   If command complains that it couldn't find fontconfig.config.
   
   
   locate fontconfig.config (e.g. if it is shown to be in /etc/java-6-openjdk/fontconfig.properties)
   
   The other file fontconfig.bfc might also be here:
   
   
   sudo java -jar compilefontconfig.jar /etc/java-6-openjdk/fontconfig.properties fontconfig.bfc
   
   

2. Set your JAVA_HOME

   From <Bitbucket Server installation directory>/bin/catalina.sh, set the right value for this variable. Below the contents of this file:

   # JAVA_HOME Must point at your Java Development Kit installation.
   # Required to run the with the "debug" argument.
   #
   # JRE_HOME Must point at your Java Runtime installation.
   # Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME
   # are both set, JRE_HOME is used.
