javac CRASH

[Ulf Zibis]

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.

Thanks for those valuable hints.
I would like to see those explicitly in make/build.properties.
