Description Jesse Glick 2001-10-22 12:58:55 UTC 
If you assume java.version means anything, you may be wrong. It is not
guaranteed to be in any particular format. java.specification.version
is more reliable; to use this, it is easiest to use code such as:

import org.openide.modules.*;
if (Dependency.JAVA_SPEC.compareTo(new SpecificationVersion("1.3")) >= 0) {
    // 1.3 or higher
} else {
    // pre-1.3
}

The following classes are possible offenders:

org.netbeans.modules.debugger.support.util.Utils
org.netbeans.modules.debugger.support.java.JavaElementSelector
org.netbeans.modules.debugger.jpda.Launcher
Comment 1 Daniel Prusa 2001-10-23 12:56:50 UTC 
Fixed in JavaElementSelector and Launcher.

In Utils we need to detect java version rather than specification 
version to set classic switch appropriately to avoid some serious 
problems with debugging on HotSpot.
