Seems this change made something not happy on the JDK1.4 that Gump runs
(namely, that below). Does the bootstrap-ant script need to be aware of some
conditional compilation?
---------------------------------------------
... Bootstrapping Ant Distribution
... Compiling Ant Classes
src/main/org/apache/tools/ant/taskdefs/condition/IsPingable.java:81: cannot
resolve symbol
symbol : method isReachable (int)
location: class java.net.InetAddress
return address.isReachable(timeout*1000);
^
Note: Some input files use or override a deprecated API.
Note: Recompile with -deprecation for details.
1 error
... Failed compiling Ant classes !
---------------------------------------------
