Comments
EVALUATION This bug is a regression introduced by the fix for 6366440 [Application deadlocks when printing some text through JTextPane] After that fix we started to check whether we need to set attributes for style. The logic is we set attribute if the current value is different for the new one. The problem is we used StyleConstants.getFoo to get the current value of attributes. StyleConstants returns some default values in case attribute is not define. In case the default value is the same as the one we want to set the attribute to the attribute will not be set. In the case of this bug FontSize attribute is not initialized because StyleConstants.getFontSize returns 12 in case this attribute is not defined and FontSize we want to initialize style with happened to be 12 too. We need to fetch attributes directly from style instead of using StyleConstants.getFoo for that.
