javac CRASH

[Jonathan Gibbons]

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.

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. ]
