[ANNOUNCEMENT] Apache Commons Math 3.4 Released

[Luc Maisonobe]

The Apache Commons Team is pleased to announce the availability of
Apache Commons Math 3.4.

Apache Commons Math is a library of lightweight, self-contained
mathematics and statistics components addressing the most common
problems not available in the Java programming language or Commons Lang.

Version 3.4 is a minor release: It combines bug fixes and new features.
Changes to existing features were made in a backwards-compatible way
such as to allow drop-in replacement of the v3.3 JAR file. Most notable
among the new features are: new distributions (Gumbel, Laplace,
Logistic, Nakagami), and improvements on percentiles algorithms (better
handling for NaNs in the regular algorithm, plus a new storeless
implementation). Bicubic and tricubic interpolators have been fixed and
new implementations added. There have been numerous bug fixes and
several improvements on performances or robustness. The minimum version
of the Java platform required to compile and use Apache Commons Math is
Java 5. Users are encouraged to upgrade to this version as this release
not only includes bug fixes but also deprecates numerous classes and
methods that will be deleted from the next major release (4.0).

A full list of all changes can be found in the release notes at
  http://www.apache.org/dist/commons/math/RELEASE-NOTES.txt

Source and binary distributions are available for download from the
Apache Commons download site:

at the above location when downloading the release.

Maven artifacts are also available in the maven central repository:

  GroupId:org.apache.commons
  ArtifactId: commons-math3
  Version:3.4

Re: [vfs] How to properly clear VFS Ram filesystem

[Bernd Eckenfels]

Hello,

there are a number of leak fixes in the trunk (upcoming 2.1), this
might be needed to get the close really purge the cache. Arbi, can you
check and let us know if it works in 2.0 and if not, if 2.1 is fine?

(and yes, I also wonder why we have no .close() on FileSystem :) 

Gruss
Bernd

 FileSystemManager manager = VFS.getManager();
 FileObject root = manager.resolveFile(ram:/);
 manager.closeFileSystem(root.getFileSystem());
 
 should do the trick.
