java version "1.8.0_201"

Description

Steps to Reproduce

• Start Karaf 4.1.4 on Windows
• Put custom-realm.xml in the hot deployment directory. This is more or less the minimal example for PropertiesLoginModule that is documented in the Manual
• In the Karaf shell, use jaas:realm-manage --index 6 followed by jaas:user-list to obtain the list of users.
• compare the output to the results for the default PropertiesLoginModule (use jaas:realm-manage --index 1 followed by jaas:user-list)

Expected Behavior

The outputs should match

Actual Results

The replicated PropertiesLoginModule configuration returns an empty listing. This seems to be the normal result, when the users-file is not found.

I get this output:

karaf@root()> env karaf.etc
String          karaf.etc       C:\r1\t1\n1\2\apache-karaf-4.1.4\etc

karaf@root()> jaas:realm-list
Index | Realm Name | Login Module Class Name
------+------------+---------------------------------------------------------------
1     | karaf      | org.apache.karaf.jaas.modules.properties.PropertiesLoginModule
2     | karaf      | org.apache.karaf.jaas.modules.publickey.PublickeyLoginModule
3     | karaf      | org.apache.karaf.jaas.modules.audit.FileAuditLoginModule
4     | karaf      | org.apache.karaf.jaas.modules.audit.LogAuditLoginModule
5     | karaf      | org.apache.karaf.jaas.modules.audit.EventAdminAuditLoginModule
6     | my-realm   | org.apache.karaf.jaas.modules.properties.PropertiesLoginModule
karaf@root()> jaas:realm-manage --index 6

karaf@root()> jaas:user-list
User Name | Group | Role
----------+-------+-----


karaf@root()> jaas:realm-manage --index 1 --force

karaf@root()> jaas:user-list
User Name | Group      | Role
----------+------------+--------------
karaf     | admingroup | admin
karaf     | admingroup | manager
karaf     | admingroup | viewer
karaf     | admingroup | systembundles
karaf     | admingroup | ssh

Additional Information

The problematic part is the users configuration in custom-realm.xml

Compare

karaf@root()> env karaf.etc
String          karaf.etc       C:\r1\t1\n1\2\apache-karaf-4.1.4\etc

to the values obtained when debugging PropertiesBackingEngineFactory:

This issue seems to have existed in the past (KARAF-2226), but the described workaround does not exist anymore and was deleted from the documentation (KARAF-3162)
