Summary: Improving Windows tools.jar locator
Initial Comment:
Although the current logic is good and works in almost
all cases, it would be nice to improve it. There are
several new considerations.
- We need to check for jdk<version> as well as
j2sdk<version>, since 1.5 will install there by default.
- The default location for jdk 1.4.2_04 installations
is %ProgramFiles%\Java\j2sdk1.4.2_04 rather than
C:\j2sdk1.4.2_04 (I'm pretty sure this holds for all
the recent versions of the jdk), so for users who
accept the default installation, DrJava will fail to
find their tools.jar. A good location to check, given
the default install directories, would be <Java
Home>\..\j2sdk<version>.
- The current logic only looks in C:\j2sdk<version>,
and will not check any other drives. I'm not sure if
there's a way to check for other fixed disks, but it
makes sense to check some more locations, including
%homedrive% and the drives from in %windir% and
%programfiles%.
I wrote these in order of importance, as I see it. I
think supporting jdk1.5 in this way is important (and
easy). We also shouldn't have trouble just because of
more recent installations of the jdk, and this is also
a pretty easy change. The last one is pretty
unimportant, as it only affects people who have a
non-default windows installation (or java
installation), and people who install their programs in
a non-default location are probably people who can
handle locating their own tools.jar. Still, it'd be
nice to make the ToolsJarClassLoader a little more
robust, so I figured I'd include it here.
