the use of a variable named newField in templates throws a strange exception

Hi,

I wrote this template:

`${result:newName(Class)} ${newField} = (${result}) Factory.CreateObject(${result}.class);`

I wasn't able to use it because I had this exception:
`class org.eclipse.jdt.internal.corext.template.java.JavaContext cannot be cast to class org.eclipse.jdt.internal.corext.template.java.JavaPostfixContext (org.eclipse.jdt.internal.corext.template.java.JavaContext and org.eclipse.jdt.internal.corext.template.java.JavaPostfixContext are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @4d097a89)`

I think it could be easier to use if the error explained the situation better.

Thank you
