Some of those programs are provided under licenses deemed +incompatible with the GPLv2 by the Free Software Foundation and others. +For example, the package includes programs licensed under the Apache +License, Version 2.0 and may include FreeType. Such programs are licensed +to you under their original licenses. + +Oracle facilitates your further distribution of this package by adding the +Classpath Exception to the necessary parts of its GPLv2 code, which permits +you to use that code in combination with other independent modules not +licensed under the GPLv2. However, note that this would not permit you to +commingle code under an incompatible license with Oracle's GPLv2 licensed +code by, for example, cutting and pasting such code into a file also +containing Oracle's GPLv2 licensed code and then distributing the result. + +Additionally, if you were to remove the Classpath Exception from any of the +files to which it applies and distribute the result, you would likely be +required to license some or all of the other code in that distribution under +the GPLv2 as well, and since the GPLv2 is incompatible with the license terms +of some items included in the distribution by Oracle, removing the Classpath +Exception could therefore effectively compromise your ability to further +distribute the package. + +Failing to distribute notices associated with some files may also create +unexpected legal consequences. + +Proceed with caution and we recommend that you obtain the advice of a lawyer +skilled in open source matters before removing the Classpath Exception or +making modifications to this package which may subsequently be redistributed +and/or involve the use of third party software. diff -r 474cec233fb2 -r 0c0b618a20b1 make/MacBundles.gmk --- a/make/MacBundles.gmk Fri Dec 15 11:23:50 2017 -0500 +++ b/make/MacBundles.gmk Fri Dec 15 16:54:17 2017 +0100 @@ -1,5 +1,5 @@ # -# Copyright (c) 2011, 2016, Oracle and/or its affiliates.

A version number, {@code $VNUM}, is a non-empty sequence of + * elements separated by period characters (U+002E). An element is either + * zero, or an unsigned integer numeral without leading zeros. The final + * element in a version number must not be zero. When an element is + * incremented, all subsequent elements are removed. The format is:

+     * [1-9][0-9]*((\.0)*\.[1-9][0-9]*)*

The sequence may be of arbitrary length but the first three - * elements are assigned specific meanings, as follows:

+ *

The sequence may be of arbitrary length but the first four elements + * are assigned specific meanings, as follows:

* * 
-     *     $MAJOR.$MINOR.$SECURITY
+     * $FEATURE.$INTERIM.$UPDATE.$PATCH
      *
* *
    * - *

  • {@code $MAJOR} --- The major version - * number, incremented for a major release that contains significant new - * features as specified in a new edition of the Java SE Platform - * Specification, e.g., JSR 337 for - * Java SE 8. Features may be removed in a major release, given - * advance notice at least one major release ahead of time, and - * incompatible changes may be made when justified. The {@code $MAJOR} - * version number of JDK 8 is {@code 8}; the {@code $MAJOR} version - * number of JDK 9 is {@code 9}. When {@code $MAJOR} is incremented, - * all subsequent elements are removed.

    • + *

  • {@code $FEATURE} — The + * feature-release counter, incremented for every feature release + * regardless of release content. Features may be added in a feature + * release; they may also be removed, if advance notice was given at least + * one feature release ahead of time. Incompatible changes may be made + * when justified.

    • * - *

  • {@code $MINOR} --- The minor version - * number, incremented for a minor update release that may contain - * compatible bug fixes, revisions to standard APIs mandated by a - * Maintenance Release - * of the relevant Platform Specification, and implementation features - * outside the scope of that Specification such as new JDK-specific APIs, - * additional service providers, new garbage collectors, and ports to new - * hardware architectures.

    • + *

  • {@code $INTERIM} — The + * interim-release counter, incremented for non-feature releases that + * contain compatible bug fixes and enhancements but no incompatible + * changes, no feature removals, and no changes to standard APIs. + *

    • * - *

  • {@code $SECURITY} --- The security - * level, incremented for a security update release that contains critical - * fixes including those necessary to improve security. {@code $SECURITY} - * is not reset when {@code $MINOR} is incremented. A - * higher value of {@code $SECURITY} for a given {@code $MAJOR} value, - * therefore, always indicates a more secure release, regardless of the - * value of {@code $MINOR}.

    • + *

  • {@code $UPDATE} — The update-release + * counter, incremented for compatible update releases that fix security + * issues, regressions, and bugs in newer features.

    • + * + *

  • {@code $PATCH} — The emergency + * patch-release counter, incremented only when it's necessary to produce + * an emergency release to fix a critical issue.

    • * *
* - *

The fourth and later elements of a version number are free for use - * by downstream consumers of this code base. Such a consumer may, - * e.g., use the fourth element to identify patch releases which - * contain a small number of critical non-security fixes in addition to - * the security fixes in the corresponding security release.

+ *

The fifth and later elements of a version number are free for use by + * platform implementors, to identify implementor-specific patch + * releases.

* - *

The version number does not include trailing zero elements; - * i.e., {@code $SECURITY} is omitted if it has the value zero, - * and {@code $MINOR} is omitted if both {@code $MINOR} and {@code - * $SECURITY} have the value zero.

+ *

A version number never has trailing zero elements. If an element + * and all those that follow it logically have the value zero then all of + * them are omitted.

* *

The sequence of numerals in a version number is compared to another * such sequence in numerical, pointwise fashion; e.g., {@code - * 9.9.1} is less than {@code 9.10.3}. If one sequence is shorter than - * another then the missing elements of the shorter sequence are - * considered to be less than the corresponding elements of the longer - * sequence; e.g., {@code 9.1.2} is less than {@code 9.1.2.1}. - *

+ * 10.0.4} is less than {@code 10.1.2}. If one sequence is shorter than + * another then the missing elements of the shorter sequence are considered + * to be less than the corresponding elements of the longer sequence; + * e.g., {@code 10.0.2} is less than {@code 10.0.2.1}.
