This article explains how we resolve the 500 error while running the Dataplane report, and in the logs, we see, “Java is unable to locate its standard font library”.

## \uD83D\uDCD8 Instructions

This problem is mostly caused due to missing Java fonts after installing a new OpenJDK version, or after moving to a new server.


1. Install fontconfig by running the below commands with the respective OS

#### Ubuntu 

```
sudo apt install -y fontconfig
```

#### CentOS 7

```
sudo yum install -y dejavu-sans-fonts
```

#### CentOS 6

```
sudo yum install -y fontconfig dejavu-sans-fonts
```

#### RHEL 

```
sudo yum install fontconfig
```

#### Debian 

```
apt-get update && apt-get install -y fontconfig
```

#### Fedora

```
dnf install -y fontconfig
```


2. Restart each Jira Data Center Node/Server.
