                * java/lang/Byte.java (static): initialize byteCache.
                (valueOf(String,int)): use valueOf(byte) rather than new.
                (valueOf(String)): likewise.
                (valueOf(byte)): Switch from lazy initialization of cached 
values to
                initialization at class initialization time. This removes the 
need for
                synchronization in the common case.
                (decode): use valueOf(byte) rather than new.
                * java/lang/Character.java (static): initialize charCache.
                (valueOf): Switch from lazy initialization of cached values to
                initialization at class initialization time. This removes the 
need for
                synchronization in the common case.
                * java/lang/Double.java (ZERO): new private field.
                (ONE): likewise.
                (valueOf(double)): don't create new doubles for the case of 0 
and 1.
                (valueOf(String)): use valueOf(double) rather than new.
                (equals): use raw bits for comparison to avoid division.
                * java/lang/Float.java (ZERO): new private field.
                (ONE): likewise.
                (valueOf(float)): don't create new floats for the case of 0 and 
1.
                (valueOf(String)): use valueOf(float) rather than new.
                (equals): use raw bits for comparison to avoid division.
                * java/lang/Integer.java (static): initialize intCache.
                (stringSize): new private method to estimate size of string for 
an int.
                (toString): reuse digits for single character strings, for 
multiple
                character strings estimate their length using string size 
method.
                (valueOf(String,int)): use valueOf(int) rather than new.
                (valueOf(String)): likewise.
                (valueOf(int)): Switch from lazy initialization of cached 
values to
                initialization at class initialization time. This removes the 
need for
                synchronization in the common case.
                (getInteger): use valueOf(int) rather than new.
                (decode): use valueOf(int) rather than new.
                (signum): use shift and subtract to compute value.
                (toUnsignedString): calculate string size rather than using 32 
chars.
                * java/lang/Long.java (longCache): new private field.
                (stringSize): new private method to estimate size of string for 
a long.
                (toString): reuse digits for single character strings, for 
multiple
                character strings estimate their length using string size 
method.
                (valueOf(String,int)): use valueOf(long) rather than new.
                (valueOf(String)): likewise.
                (valueOf(long)): use cache of values.
                (decode): use valueOf(long) rather than new.
                (signum): use shift and subtract to compute value.
                (toUnsignedString): calculate string size rather than using 64 
chars.
                * java/lang/Short.java (static): initialize shortCache.
                (valueOf(String,int)): use valueOf(short) rather than new.
                (valueOf(String)): likewise.
                (valueOf(short)): Switch from lazy initialization of cached 
values to
                initialization at class initialization time. This removes the 
need for
                synchronization in the common case.
                (decode): use valueOf(short) rather than new.
