Fuse 7.x basically uses the same version as Keycloak, into other words,
`bcprov-jdk15on` version 1.60. The error reported here:
https://issues.jboss.org/browse/KEYCLOAK-8926 is related with the fact
that Bouncycastle was not being loaded during the boot time. If we look
at the logs we can find:
```
12:30:15 Red Hat Fuse starting up. Press Enter to open the shell now...
12:30:15 Unable to register security provider:
java.lang.ClassNotFoundException:
org.bouncycastle.jce.provider.BouncyCastleProvider
```
By changing `CustomFuseContainer` we will notice that the issue is
gone, because now Bouncycastle, which comes with Fuse distribution is
being added.
