[jboss-jira] [JBoss JIRA] Updated: (JASSIST-37) CtField.getConstantValue() for just added fileds

[Vlad Skarzhevskyy (JIRA)]

     [ http://jira.jboss.com/jira/browse/JASSIST-37?page=all ]

Vlad Skarzhevskyy updated JASSIST-37:
-------------------------------------

    Workaround Description: 
The problem was field.setModifiers() was not called before klass.addField(field, initializer);
So initializer was not suppose to be created. Later filed was modified to static final. But this does not affect initializer
               Description: 
I'm creating tool to verify Java API compatibility

I'm converting  class files to XML and then XML to classes creating CtClass objects that have empty implementation.

Then target is to compare new lib version to API described in XML.

project site: http://pyx4me.com/snapshot/jour/signature.html

This is what causing the problem:

CtField field =  new CtField(CtClass.longType, "test", klass);
CtField.Initializer initializer = CtField.Initializer.constant(1);
klass.addField(field, initializer);

// Then later when
Object value = field.getConstantValue();
//value is always null and can't be used for comparison.

when I  call klass.writeFile(); The .class is created correctly and when decompiled I see that int filed is properly initialized .

BUT When javassist  loads again the generated classes field.getConstantValue(); still null!
