A DESCRIPTION OF THE PROBLEM :
The path to a jaas.conf file, located outside a jar, cannot contain spaces or it will fail.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a folder named "conf" and place jaas.conf within the "conf" folder.
Create an executable jar with a java class containing the following code:
System.setProperty( "java.security.auth.login.config", Class.forName("MyClass").getResource("conf/jaas.conf").toString( ) );
Place the jar in a folder whose name contains spaces.
Place "conf" folder in same folder as the jar.
Execute the jar.

--ISSUE--
The jaas.conf cannot be found.
--ISSUE--

Workaround 1:
Place "conf" folder within jar. No more issues.

Workaround 2:
Rename all folders in path to jar to eliminate spaces (all the way to root or drive letter). No more issues.

EXPECTED -
I was expecting the jaas.conf to be found.
ACTUAL -
The jaas.conf file cannot be found.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
Include this anywhere in your class. Replace "MyClass", "MyRealm", and "MyKDC" with appropriate values:

System.setProperty( "java.security.auth.login.config", Class.forName("MyClass").getResource("conf/jaas.conf").toString( ) );
System.setProperty( "java.security.krb5.realm", "MyRealm" );
System.setProperty( "java.security.krb5.kdc", "MyKDC" );

LoginContext context = new LoginContext( "Kerberos", new DialogCallbackHandler( ) );
context.login( );
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Workaround 1:
Place "conf" folder within jar. No more issues.

Workaround 2:
Rename all folders in path to jar to eliminate spaces (all the way to root or drive letter). No more issues.
