I came across a problem where compiler suggested use is an
error. In gerneric array example I used the required
suggestion and I got an generic array creation error.
I discussed this problem with Peter. He suggested me
to file RFE to improve diagnostics.

Ex:

../../../src/share/classes/com/sun/tools/jdi/LinkedHashMap.java:286:
warning: [unchecked] unchecked conversion
found : com.sun.tools.jdi.LinkedHashMap.Entry[]
required: com.sun.tools.jdi.LinkedHashMap.Entry<K,V>[]
          Entry<K,V> newMap[] = new Entry[newCapacity];

 ../../../src/share/classes/com/sun/tools/jdi/LinkedHashMap.java:147:
 generic array creation
          table = new Entry<K,V>[initialCapacity];
