Warning without cleanbuild

[Sebastian Sickelmann]

Hi,

i sometimes get this warning if i don't execute a "make clean" before my 
"make all" in jdk repository.

I uploaded the complete messages here.
http://oss-patches.24.eu/openjdk8/warningWithoutCleanBuild.log

last time it happend after i updated to 46b53f80ab0a of 
http://hg.openjdk.java.net/jdk8/tl/jdk/ and import the following 2 patches
http://oss-patches.24.eu/openjdk8/InternalError/part1/REBASED_ON_46b53f80ab0a/openjdk8-jdk-only.patch
http://oss-patches.24.eu/openjdk8/InternalError/part2/REBASED_ON_46b53f80ab0a/openjdk8-jdk-only.patch

you can maybe reproduce it with the following sequence:
hg update -r 46b53f80ab0a
make clean
make all
hg import --no-commit 
http://oss-patches.24.eu/openjdk8/InternalError/part1/REBASED_ON_46b53f80ab0a/openjdk8-jdk-only.patch
make all
hg import --force --no-commit 
http://oss-patches.24.eu/openjdk8/InternalError/part2/REBASED_ON_46b53f80ab0a/openjdk8-jdk-only.patch
make all  --->> Warning

Is it my Patch? But why?
or is there something in the buildscript that does not recompile 
dependencies correctly? may i expect that the build skript should handle 
that correctly?
