3.2

The contributed classpath variables like JUNIT_HOME or JRE_SRC are not meant to be modified. If a user does it, the value will be overridden the next time Eclipse starts and the variable initialializer is called.
In the UI we want to know which variables are 'read-only' so we can block the 'Edit' button.

- suggest an addition the classpath variable initialializer extension point: an optional attribute
 or
a method to reimplement on ClasspathVariableInitializer
- API to get this information:
JavaCore.isClasspathVariableModifiable(String name) or, to solve more outstanding issues:
something like
JavaCore.getClasspathVariableDescription(varName) : ClasspathVariableDescription
ClasspathVariableDescription
  getName, get/setValue, add/removeChangeListener, isDeprecated, isModifiable

see also bug 138599 for other requests regarding classpath variables

Unfortunately, I had not enough time to implement this requirement for 3.3 M3.
Need to make decision for M4 if this bug will still stay in plan or not...
