Hello. I recently found suspicious field (with SpotBugs help) in class SunFontManager: static HashMap<String, FamilyDescription> platformFontMap; This HashMap is accessed (read and write) in a method sun.font.SunFontManager#findFontFromPlatformMap. As I see there is no synchronization when this HashMap is accessed. This method can be called from client code with this simple stack trace: at sun.font.SunFontManager.findFontFromPlatformMap(SunFontManager.java:1508) at sun.font.SunFontManager.findFont2D(SunFontManager.java:2069) at java.awt.Font.getFont2D(Font.java:500) at java.awt.Font.getPSName(Font.java:1416) I wonder if this unsynchronized access is expected. Looks like it can break things when accessed from multiple threads simultaneously. Do I miss something? Is it done this way, because Font objects are supposed to be accessed from a single thread only? Andrey Turbanov
