Flash Builder 4.7 Freezes Opening MXML

Why does Flash Builder 4.7 freeze when I try to open an MXML file?
There is a bug in the Flash Builder compiler when processing MXML components that are nested so that a component has a child that contains a reference to the parent component's type.  Adobe did send me a fix for this issue.
Steps to fix the issue:
  1. Close Flash Builder
  2. In Windows Explorer navigate to the c:/Program Files/Adobe Flash Builder 4.7/eclipse/plugins/com.adobe.flash.compiler_4.7.0.349722/AIRSDK/lib
  3. Copy the compiler.jar file to a directory in case you need to replace it.
  4. Download the patched compiler.jar I received from Adobe to the directory above
  5. Start Flash Builder

  2. Download the patched compiler.jar I received from Adobe to the directory above Point No.4 compiler.jar on click of it it shows 404 Error.....

  3. URL for compiler jar has been updated.

  4. Where can we download compiler.jar right now?. We need it.

  5. Yes. Can we have the compiler.jar? Seems I am not the only one that still uses FB?
