There is set wrong default relative-to path for CredentialStore.
Default relative-to path is set to folder from which we started EAP server.

e.g.:

• cd EAP_FOLDER
• ./bin/standalone.sh
• relative-to is se to EAP_FOLDER
  or
• cd EAP_FODER/bin
• ./standalone.sh
• relative-to is se to EAP_FOLDER/bin

How to reproduce

/subsystem=elytron/credential-store=cs007:add(uri="cr-store://test/keystorecs007.jceks?create=true", credential-reference= {clear-text=pass123})

/subsystem=elytron/credential-store=cs007/alias=newCs007:add(secret-value=Elytron)

Now you can see in EAP_FOLDER (it can be different, see above) keystorecs007.jceks file
I would expect this file in data directory of server.
