As it stands, the jdk14 and jdk15 ports register a static dependency on
the default bootstrap unconditionally. Portmanager ( I assume
portmaster behave similarly ) parses the Makefiles for all installed
ports so that it can take environment settings and options into account
and then handles the building of each port separately. In the case of
the jdk ports, it always sees a dependency on the default bootstrap.
This means that the default bootstrap must be installed and current
before it will update the jdk ports, even if it is a rebuild which may
be bootstrapped by itself.
The proposed patch above, does resolve this issue, however it doesn't
allow for an accurate dependency registration of the bootstrap that was
actually used to build the port. In the case of jdk14 this is fine
because only two possible bootstraps exist, linux or itself. For jdk15,
where five possible bootstraps exist we may not accurately record the
bootstrap that was used for the build. Since diablo is the highest
priority bootstrap for jdk15, if it is installed it will be used in
preference of all others, but no dependency would be registered on it.
