- * The LineBreakMeasurer is used for calculating text bounds.
- * The last official JDK 6 version (1.6.0_45) and also JDK 7 (1.7.0_21)
- * for Windows are affected. For JDK 7 - update to a more recent version.
- * For JDK 6 - replace the fontmanager.dll with the previous release (1.6.0_43).
- *
- * For performance reasons, this method only checks for a windows jvm
- * with version 1.6.0_45 and 1.7.0_21.
- *
- * Set system property "org.apache.poi.JvmBugs.LineBreakMeasurer.ignore" to "true"
- * to bypass this check and use the normal fonts.
- *
- * @return true, if jvm is bugged, caller code should use Lucida Sans
- * instead of Calibri and Lucida Bright instead of Cambria
- *
