We need to squash our build warning, both JPRT-generated, and otherwise. For example:

c:\jprt\T\P1\021411.jcg-int\s\build\windows-x86-normal-clientANDserver-release\install\tmp\ishield\patch\jre.xml(63) : warning CNDL1044 : The Directory/@ShortSourceName attribute's value 'ALLUSE~1' is an ambiguous short name because it ends with a '~' character followed by a number. Under some circumstances, this name could resolve to more than one file or directory name and lead to unpredictable results (for example 'MICROS~1' may correspond to 'Microsoft Shared' or 'Microsoft Foo' or literally 'Micros~1').
c:\jprt\T\P1\021411.jcg-int\s\build\windows-x86-normal-clientANDserver-release\install\tmp\ishield\patch\jre.xml(64) : warning CNDL1044 : The Directory/@ShortSourceName attribute's value 'Admint~1' is an ambiguous short name because it ends with a '~' character followed by a number. Under some circumstances, this name could resolve to more than one file or directory name and lead to unpredictable results (for example 'MICROS~1' may correspond to 'Microsoft Shared' or 'Microsoft Foo' or literally 'Micros~1').
c:\jprt\T\P1\021411.jcg-int\s\build\windows-x86-normal-clientANDserver-release\install\tmp\ishield\patch\jre.xml(65) : warning CNDL1044 : The Directory/@ShortSourceName attribute's value 'APPLIC~1' is an ambiguous short name because it ends with a '~' character followed by a number. Under some circumstances, this name could resolve to more than one file or directory name and lead to unpredictable results (for example 'MICROS~1' may correspond to 'Microsoft Shared' or 'Microsoft Foo' or literally 'Micros~1').

Particularly concerning are the ICE/Wix warnings and Error.
