-------------------------------------
Summary: Using wrong LaF getDefaults() method slows down startup
Key: NETBEANS-3664
URL: https://issues.apache.org/jira/browse/NETBEANS-3664
Project: NetBeans
Issue Type: Bug
Reporter: Karl Tauber
There are (at least) two places where
{{UIManager.getLookAndFeel().getDefaults()}} is used to get look and feel UI
defaults.
But this method creates a new hash table with about 600+ entries filled with
colors, icons, fonts, insets, etc., which takes some milliseconds. In case of
FlatLaf, also several properties files are read and parsed.
The javadoc of {{LookAndFeel.getDefaults()}} also states that this method
should only be invoked by the {{UIManager}}.
The correct method to use would be {{UIManager.getLookAndFeelDefaults()}},
which returns an existing hash table that was created earlier with
{{LookAndFeel.getDefaults()}}.
I'll create a PR to fix this...
