Jon,
thanks for 1st clarification.
I have
bootstrap.jdk=C:/Programme/Java/jdk1.7.0
in ${user.home}/.openjdk/build.properties instead of boot.javac.target.
Why 2 different names for the same thing?
So I guess, settings for boot.javac.source and boot.javac.target should
be better located in ${user.home}/.openjdk/langtools-build.properties,
than in
${user.home}/.openjdk/build.properties ?
For NetBeans "Clean and Build" settings for boot.javac.source and
boot.javac.target in ${user.home}/.openjdk/*build.properties don't seem
to be necessary, and regrettably settings for:
javac.source = 6
javac.target = 6
don't work, either in
make/netbeans/langtools/nbproject/private/langtools.properties. I had to
set them in build.properties.
I'm not happy to use NetBeans Properties box under Tools> Options>
Miscellaneous> Ant, because those settings are for ALL NetBeans projects.
IMO best location would be:
make/netbeans/langtools/nbproject/private/langtools.properties. In
make/netbeans/langtools/build.xml they should be loaded before:
<import file="../../build.xml"/>
Please add NetBeans project specific hints in make/build.properties.

Ulf,
Your settings for boot.java.home and target.java.home look OK.
The intent of the build is that while building the bootstrap compiler,
the settings for boot.javac.source and boot.javac.target should be
active and these are correctly set to 6 in
langtools/make/build.properties. I will investigate why these might
not be in use later today, when I have easy access to a Windows machine.
Separately, I also note that the intent is that you should not *need*
to edit langtools/make/build.properties, although it is not incorrect
to do so. But, it can lead to accidents if you might be committing and
pushing changes. To minimize that risk, you can provide/override
values in a number of ways:
-- on the Ant command line (if you invoke Ant directly)
-- in NetBeans, in the Properties box under Tools> Options>
Miscellaneous> Ant
-- in a new unmanaged file langtools/build.properties (note no make/
component)
-- in ${user.home}/.openjdk/langtools-build.properties
-- in ${user.home}/.openjdk/build.properties
The last two choices allow you to set values to be shared by multiple
repositories.
Thanks for those valuable hints.
I would like to see those explicitly in make/build.properties.

There is no make/build.properties in the jdk/ repository because that
repository uses "make" instead of "ant" for building. To build the
jdk repository, you will need either MKS or Cygwin installed on your
system. For more info, see the notes on the OpenJDK web pages. There
are NetBeans projects for selected parts of the jdk/ to make it easy
to work on small subsystems. However, I don't believe those (NetBeans)
projects are being actively maintained at this point. [This does not
apply to the langtools/ files. ]

Jon,
that would be great.
I've found out a solution, but I'm not sure, if this is as designed.
In path_to_jdk7_sources\langtools\make\build.properties I set:
boot.java.home = C:/Programme/Java/jdk1.6.0_14
target.java.home = C:/Programme/Java/jdk1.7.0
javac.source = 6
javac.target = 6
I'm wondering, that there is no ...\make\build.properties file in
tl/jdk tree.
Maybe you like to have a look on ...\make\netbeans\charset\* in my
patch for https://bugs.openjdk.java.net/show_bug.cgi?id=100098 ?

Rémi,
Thanks for the heads up. I'll check this out. It is still the case
that you should only need 1.6 to build langtools.

Jonathan,
thanks for additional help.
Now I tried:
C:\Projects\OpenJDK7\langtools\make>"C:\Programme\Java\NetBeans
6.7.1\java2\ant\
bin\ant" -Dboot.java/home=C:/Programme/Java/jdk1.7.0
I've noticed that.
You have to run ant with jdk7.
JAVA_HOME=C:/Programme/Java/jdk1.7.0
ant -Dboot.java/home=C:/Programme/Java/jdk1.7.0
Jon, it seems the ant build script need be updated because
we are not able to compile with jdk6 anymore.
The bootstrap javac/javap/etc should be built with -source 1.6
-target 1.6.
