Some entries in src/java.desktop/share/conf/psfontj2d.properties contain duplicate font mappings with identical keys and values. These duplicates are redundant and can be safely removed to improve the clarity and maintainability of the font configuration.

Duplicate Entry:
itcavantgarde=avantgarde_book
This mapping appears more than once in the file and points to the same font resource. The entry has now been retained only once. This cleanup does not impact font functionality or behavior but helps eliminate unnecessary duplication in the configuration.

Affected file:
src/java.desktop/share/conf/psfontj2d.properties
