-------------------------------------

             Summary: ValueMap doesn't support primitive types
                 Key: SLING-2712
                 URL: https://issues.apache.org/jira/browse/SLING-2712
             Project: Sling
          Issue Type: Improvement
          Components: JCR
    Affects Versions: JCR Resource 2.2.4
            Reporter: Simone Tripodi
             Fix For: JCR Resource 2.2.4


I have a {{Resource}} which has a property named {{releaseMonth}} which is of type {{long}}; then I have a simple {{NumberFormat}}

{code}
NumberFormat numberFormat = new DecimalFormat("00");
{code}

If I try to execute, in a JSP, the following code, to cast the {{releaseMonth}} property to the primitive {{long.class}}:

{code}
<%= numberFormat.format(properties.get("releaseMonth", long.class)) %>
{code}

It throws an exception:

{code}
Caused by: java.lang.IllegalArgumentException: Cannot format given
Object as a Number

{code}

If I use instead the primitive wrapper {{Long.class}}

{code}
<%= numberFormat.format(properties.get("releaseMonth", Long.class)) %>
{code}

everything works fine.

Looks like that

{code}
properties.get("", long.class)
{code}

gets {{NULL}} back
