Hi all,

I have a rather large project which gives no errors in Eclipse.
However, if I try to compile it from the command line, I get a huge
bunch of errors.

I pick out a few:
org/apache/commons/collections/ClosureUtils.java:196: cannot find symbol
symbol : method
getInstance(org.apache.commons.collections.Closure<capture of ? super
I>,org.apache.commons.collections.Closure<capture of ? super I>)
location: class org.apache.commons.collections.functors.ChainedClosure
        return ChainedClosure.getInstance(closure1, closure2);
                             ^
Whereas ChainedClosure definitely contains
    /**
     * Factory method that performs validation.
     *
     * @param closure1 the first closure, not null
     * @param closure2 the second closure, not null
     * @return the <code>chained</code> closure
     * @throws IllegalArgumentException if either closure is null
     */
    @SuppressWarnings("unchecked")
    public static <I> Closure<I> getInstance(Closure<? super I>
closure1, Closure<? super I> closure2) {
        if (closure1 == null || closure2 == null) {
            throw new IllegalArgumentException("Closures must not be
null");
        }
        Closure<I>[] closures = new Closure[] { closure1, closure2 };
        return new ChainedClosure<I>(closures);
    }

There are quite a lot of these messages.

Another common error is this one:
org/apache/commons/collections/ComparatorUtils.java:57: incompatible
types; inferred type argument(s) java.lang.Comparable<? super T> do not
conform to bounds of type variable(s) T
found :
<T>org.apache.commons.collections.comparators.ComparableComparator<T>
required: java.util.Comparator
    public static final Comparator NATURAL_COMPARATOR =
ComparableComparator.getInstance();
                                ^

But ComparableComparator is defined like so:
public class ComparableComparator<T extends Comparable<? super T>>
implements Comparator<T>, Serializable {...

And there are more errors of this style:
org/apache/commons/collections/PredicateUtils.java:261:
<T>getInstance(org.apache.commons.collections.Predicate<? super
T>,org.apache.commons.collections.Predicate<? super T>) in
org.apache.commons.collections.functors.AndPredicate cannot be applied
to (org.apache.commons.collections.Predicate<capture of ? super
T>,org.apache.commons.collections.Predicate<capture of ? super T>)
        return AndPredicate.getInstance(predicate1, predicate2);
                           ^

This is javac:
javac -version
javac 1.5.0_07

Eclipse uses another javac (IBM???s), but it gives the same errors from
the command line.

I would be very pleased to get some hints about what I am doing wrong.

I invoke it like so:
hendrik@lichtenstein:~/Java/Jakarta Commons
Collections/commons-collections-generic-3.2-src/src/java> javac
- -classpath . org/apache/commons/collections/FunctorUtils.java

Thanks, H.
