# This file handles detection of the Boot JDK. The Boot JDK detection
|
|
# process has been developed as a response to solve a complex real-world
|
|
# problem. Initially, it was simple, but it has grown as platform after
|
|
# platform, idiosyncracy after idiosyncracy has been supported.
|
|
#
|
|
# The basic idea is this:
|
|
# 1) You need an acceptable *) JDK to use as a Boot JDK
|
|
# 2) There are several ways to locate a JDK, that are mostly platform
|
|
# dependent **)
|
|
# 3) You can have multiple JDKs installed
|
|
# 4) If possible, configure should try to dig out an acceptable JDK
|
|
# automatically, without having to resort to command-line options
|
|
#
|
|
# *) acceptable means e.g. JDK7 for building JDK8, a complete JDK (with
|
|
# javac) and not a JRE, etc.
|
|
#
|
|
# **) On Windows we typically use a well-known path.
|
|
# On MacOSX we typically use the tool java_home.
|
|
# On Linux we typically find javac in the $PATH, and then follow a
|
|
# chain of symlinks that often ends up in a real JDK.
|
|
#
|
|
# This leads to the code where we check in different ways to locate a
|
|
# JDK, and if one is found, check if it is acceptable. If not, we print
|
|
# our reasons for rejecting it (useful when debugging non-working
|
|
# configure situations) and continue checking the next one.
