label with value as zero length string reading issue

[Ritu Raj Lakhera]

Hi All,

If we use a label with value as zero length string then I think it should
be display the empty string while these label goes to use.
But currently its return the key name same as in case of key does not exist
in label file.So current result does not make sense even label key is exist.

If this behavior is not expected then I will happy to create JIRA issue.

For ex:
<property key="EmptyLabelA">
    <value xml:lang="en"></value>
</property>
<property key="EmptyLabelB">
    <value xml:lang="en"/>
</property>

I am attaching the patch for this issue with this mail.
