[fedora-java] XMvn 2.0.1 release notes

[Mikolaj Izdebski]

What's new in XMvn 2.0.1

XMvn 2.0.1 was released on 2014-06-06.  Most important changes
include:

* Minor features

  * Property to disable effective POMs

    XMvn 2.0.1 allows to globally disable generation and resolution
    of effective POMs by setting system property
    <<<xmvn.resolver.disableEffectivePom>>>

* Minor bugfixes

  * Fixed JAR post-processing during installation

    In some cases XMvn 2.0.0 may have failed to inject Javapackages
    manifest entries to JARs it installs.  It also failed to detect
    native code inside JARs.  This was fixed in XMvn 2.0.1.

  * Fixed return code of <<<xmvn-install>>>

    XMvn Installer CLI used to return zero exit code even if
    installation failed.  This was corrected in XMvn 2.0.1.

  * Implemented lazy loading of metadata

    XMvn spawns background threads to initialize some "eager"
    singletons in order to minimize delay on their first use and
    improve overall performance.  Since Java allows isolated class
    realms to have multiple singleton instances, hundreds of
    initializer threads may have be spawned in applications heavily
    using isolated realms, such as in unit testing.

    XMvn 2.0.1 implemented lazy initialization instead of eager
    initialization, which results in lower performance, but better
    worst-case behavior.

  * Fixed artifact resolution from local workspace repository

    XMvn 2.0.1 fixes a regression introduced in version 2.0.0 -
    artifacts were no longer resolved from local workspace
    repository (<<<$PWD/.m2>>>).
