This is essentially a mirror of the maven2 repository hosted at http://www.knopflerfish.org/maven2/ but more conveniently available for maven and gradle users.

More info on the different Knopflerfish maven repositories.

Fixed race condition that could cause a NullPointerException

Several broken links have been corrected and links to the bundle repository a maven2 repositories should be working again.

All source code repositories and web pages for Knopflerfish has moved to GitHub. Most web pages has been updated, but some Knopflerfish documentation still refers to the old subversion repository. The result of the nightly builds aren't published yet.

As part of the GitHub move we will close down the Knopflerfish mailing lists.

Corrected issue where the resolver under certain conditions could go into an infinite loop when a bundle wasn't resolvable.

Removed debug printout that incorrectly indicated a NPE problem.

HttpServletResponse.getLocale() incorrectly returned null if no locale had been set. Corrected to return the default locale.

Some packages from org.apache.commons added as exported by default

Property org.knopflerfish.framework.is_doublechecked_locking_safe set to true on Android by default.

Bundle repackaged to avoid class loader problems on Android

Corrected issues in the HttpServletRequest class. Some methods caused NPE or gave incorrect results during the second GET call in a Keep-Alive connection. Methods affected: getLocalAddr(), getLocalName(), getRemteAddr(), getRemoteHost(), getLocalPort(), getRemotePort().

Knopflerfish 5.2 is released and includes several minor enhancements as well as all bug fixes made since KF 5.1 was released.

• Bug fixes in the Knopflerfish OSGi framework: fixed NPR during package resolve, correcting native code checking when attaching a fragment, and corrections related to start level handling.
• Improved support for handling Android DEX files
• ART (Android runtime), the Dalvik predecessor, is now fully supported
• The Knopflerfish embedded HTTP server has been optimized to use less resources (threads & memory)
• The HTTP also has the following new features:
• Chunked transfer encoding responses
• Automatic content compression for selected content types
• Correct handling of certain HTTP/1.1 request and response headers
• Improvements to the build system to better support Android / OSGi DEX bundles.

The Release Notes include the complete list of features and fixes.

Corrected issue with NPE during package resolving or package requiring.

• Improved the configuration handling the first time a CM configuration is received to avoid unnecessary reconfigurations of the built-in default settings. This could lead to a server socket close followed by new listen on the same port.
• CM meta-data is updated to include previously undocumented configuration parameters.

• Fixed native code checking before we attach fragment.
• Changed behaviour start-up of start-level service, so that it always goes to the beginning start-level instead of last active start-level from previous run. This to comply with the OSGi Core specification.
• Limit removed on number of queued start-level operations (was 100).

Knopflerfish 5.1 is released and includes several minor enhancements as well as all bug fixes made since KF 5.0 was released. The 5.1 release also includes fixed related to Java 8 and Knopflerfish 5.1 passes all tests on Java 7 and 8 as well as older Java versions, and embedded Java profiles.

• Support for starting from a single jar that includes all jars, xargs and property files needed to start the entire system
• Knopflerfish framework can now be executed in read only mode, i.e. no files are written by the framework. This assumes bundles are installed as reference file URLs.
• UserAdmin is completely self-contained, i.e. no dependencies on KF specific bundles
• CM's persistent storage has been made more robust and fault resilient
• HTTP Server now handles chunked transfer encoding correctly
• Minor fixes in SCR
• Repository Commands supports -r flag which recursively finds and installs dependencies.

The Release Notes includes the complete list of features and fixes.

Added requirement for Meta Type service

Changed to only build all version. This makes it possible to correctly install CM-Desktop using the Repository Desktop with the Felix resolver.

UserAdmin bundle now contains and imports/exports org.knopflerfish.service.log in order to be self-contained.

Corrects issue in handling of designate-element that could cause configurations to be created, deleted or overwritten unintentionally.

Corrects issue with missing factory component check

The persistent storage of CM data has been improved to be more robust and fault resilient.

Corrected issues in the handling of chunked transfer encoding which could cause problems when transferring binary data.

When installing from a Repository and using a Resolver the confirmation pop-up dialogue will now list the additional dependencies that will be installed in order to resolve.
