Request to backport: JavaFileManager

[Joe Darcy]

The general policy for bug fixes in OpenJDK 6 is discussed on the 
project's page:
http://openjdk.java.net/projects/jdk6/

"[...] if a change is appropriate for every other JDK release train, it 
is generally appropriate for OpenJDK 6 too. Examples of such universal 
changes include security fixes and time zone information updates.

With the above caveats, bug fixes in JDK 7 that do not involve 
specification changes have presumptive validity for OpenJDK 6. That is, 
by default such fixes are assumed to be applicable to OpenJDK 6, 
especially if having "soaked" in JDK 7 for a time without incident. On a 
related point, the fixes from the stabilized HotSpot forests (for 
example HotSpot Express 14 or HotSpot Express 16) are suitable for bulk 
porting to the OpenJDK 6 HotSpot repository without review of individual 
bugs."
