Generate Java static final fields for EGL constants [RTC 32247]

Currently, from the following EGL code

library constants type BasicLibrary
const y41_True unicode(1) = "1";
const y41_False unicode(1) = "0";
const n01_True unicode(1) = "Y";
const n01_False unicode(1) = "N";
?

the following Java code is generated

public class constants_Lib extends com.ibm.javart.resources.Program
{
private static final long serialVersionUID = 70L;

public final constants_Lib ezeProgram;
public com.ibm.javart.UnicodeValue y41_005fTrue;
public com.ibm.javart.UnicodeValue y41_005fFalse;
public com.ibm.javart.UnicodeValue n01_005fTrue;
public com.ibm.javart.UnicodeValue n01_005fFalse;
?

public constants_Lib( com.ibm.javart.resources.RunUnit ru ) throws Exception
{
super( "constants_Lib", "constants", ru, false, true );
ezeProgram = this;
_runUnit().addLibrary( "constants_Lib", this );
y41_005fTrue = new com.ibm.javart.UnicodeItem( "y41_True", com.ibm.javart.Value.SQL_NOT_NULLABLE, 1, true, "U1;" );
y41_005fFalse = new com.ibm.javart.UnicodeItem( "y41_False", com.ibm.javart.Value.SQL_NOT_NULLABLE, 1, true, "U1;" );
n01_005fTrue = new com.ibm.javart.UnicodeItem( "n01_True", com.ibm.javart.Value.SQL_NOT_NULLABLE, 1, true, "U1;" );
n01_005fFalse = new com.ibm.javart.UnicodeItem( "n01_False", com.ibm.javart.Value.SQL_NOT_NULLABLE, 1, true, "U1;" );
?

We would expect the y41_ and n01_ fields to be static and final. The former, in particular, would avoid the need for new UnicodeItems in each run unit.
