Where could I find jdk 7 with (full) debug information to debug HashMap

Question

I have to debug java code, but java is not compiled with -g option (Generate all debugging information, including local variables). Someone know, where I could find complied code ready to use? Additionaly I do not look for some openJDK with -g. Also I know, I could compile it myself, but I try to avoid it.

The goal is to read a value of hash variable in debugging, it is impossible, how to do it?

Code from HashMap:

public V put(K key, V value) {
        if (table == EMPTY_TABLE) {
            inflateTable(threshold);
        }
        if (key == null)
            return putForNullKey(value);
        int hash = hash(key);
        int i = indexFor(hash, table.length);
        for (Entry<K,V> e = table[i]; e != null; e = e.next) {
            Object k;
            if (e.hash == hash && ((k = e.key) == key || key.equals(k))) {
                V oldValue = e.value;
                e.value = value;
                e.recordAccess(this);
                return oldValue;
            }
        }
        modCount++;
        addEntry(hash, key, value, i);
        return null;
    }

In your JDK installation, you have a src.zip file with all the java classes.

EDIT : Check this Where to get full source code for rt.jar?

Basically, Oracle stopped providing source code for some things. Your best shot is probably openJDK .
