Guarded code in old GUI editor created java files no longer read correctly.

I was revising an old project from 2001-2006.  It includes a number of swing forms created with the netbeans GUI editor.  These forms can no longer be read correctly.  I get an error message saying "Error while parsing java source file" see attachment below.

I think the cause of the problem is a change how guarded blocks are indicated.  In the old files, there is a space after the "//", e.g.

// GEN-BEGIN:initComponents 
// GEN-FIRST:event_formKeyPressed

Whereas the current version seems to expect no space, e.g.

//GEN-BEGIN:initComponents
//GEN-FIRST:event_formKeyPressed 

The attached project has a number of examples of forms that can no longer be read correctly.  The examples are in the directory src\main\java\jfreerails\client\view
