Revision 516518 changes the default base compile level to JDK 1.4 (for
DERBY-1983). Basically two changes:
compile.classpath now defaults to java14compile.classpath
compiler target/source flags now use 1.4 instead of 1.3
I think this change will be transparent to everyone, i.e. nothing need
change in your setup. You can remove the setting j13lib from your
ant.properties if you want though.
I think some more changes are required before the instructions can be
changed to not require jdk 1.3 and the various optional downloads, I
just need to go through the build.xml files again and see which are
still referenced & why.
Note that compile.classpath is not the same value logically as
java14compile.classpath even though the default setup makes them the
same. compile.classpath is used to compile classes that need to work in
JDK 1.4 and J2ME, whereas java14compile.classpath is used for classes
that cannot run in J2ME. I hopefully improved the comments around this
in tools/ant/properties/compilepath.properties.
Ideally one should be able to set compile.classpath to
J2ME/CDC/Foundation 1.1 + JSR 169 libraries and compile successfully.
This is to allow greater confidence that the base code will work on
JSR169 and not rely on any JDK 1.4 features. I'm not sure it that
actually works at the moment though, will be checking that later.
