Hi
While diving into meta-java I noticed the following.
The java version that is found by default in an SDK is provided by cacao-native
and the javac version by ecj-native.
Both of these are very old and I get errors if I try to compile newer java
packages as for example Ant 1.9.7.
I was wondering if this is intentional and there is something I'm missing.
In my opinion it would be better if java and javac were provided by recent
JDK/JRE like OpenJDK 8.
So in relation to my proposal to unify the virtual/java handling I think it
would make sense to clean up the java bootstrapping too.
The proposal is to not have anything from the bootstrapping process in the
PATH. This means no javac from ecj not old versions of ant, no IcedTea 7
binaries.
But only the final openjdk-8-native binaries that also provide
virtual/jdk8-native. I guess this would mean to move all the boostrap
components to a different filesystem location maybe under {sysroot_native}/opt
somewhere. IceadTea already seems build up kind of a fake-jdk by linking the
binaries. So instead of doing that ecj and cacoa could directly install to
{sysroot_native}/opt/java-bootstrap and IceadTea can then use that. Also other
bootstrap packages like old ant version could go to that location.
I attached a graphic that tries to explain how the new bootstrap process could
look like and where a host provided java would fit into that process.
Does this make sense or am I completely off?
