build failure in hotspot whitebox test support

[David Holmes]

Just did an update to my jdk7u-dev forest (first in a while) and the 
linux-i586 build fails:

Linking vm...
/java/embedded/users/dh198349/jdk7u-dev/hotspot/src/share/tools/whitebox/sun/hotspot/parser/DiagnosticCommand.java:5: 
error while writing 
sun.hotspot.parser.DiagnosticCommand.DiagnosticArgumentType: could not 
create parent directories
     public enum DiagnosticArgumentType {
            ^
1 error
make[6]: *** 
[../generated/wb/classes/sun/hotspot/parser/DiagnosticCommand.class] Error 1
make[6]: *** Waiting for unfinished jobs....

The issued command was:

/java/re/jdk/1.6.0/archive/fcs/binaries/linux-amd64/bin/javac -g 
-encoding ascii -source 6 -target 6 -sourcepath 
/java/embedded/users/dh198349/jdk7u-dev/hotspot/src/share/tools/whitebox 
-nowarn -d ../generated/wb/classes 
/java/embedded/users/dh198349/jdk7u-dev/hotspot/src/share/tools/whitebox/sun/hotspot/WhiteBox.java

and the output seems to exist:

 > dir 
b13/se-linux-i586-dh/hotspot/outputdir/linux_amd64_compiler2/generated/wb/classes/sun/hotspot/parser/
DiagnosticCommand.class
DiagnosticCommand$DiagnosticArgumentType.class
