We are please to announce that we have released the Sixth Edition of the

Armed Bear Common Lisp implementation as ABCL 1.5.0.

Due to the lack of a publicly available Java 5 implementation, with this

release we drop support for that platform, and henceforth support

running on Java 6, Java 7, and Java 8.

In addition to consolidating eight months of bug fixes, the following

notable features are now also present in the implementation.

The compiler now records more complete debugging information on the

SYS:SOURCE symbol property.

ABCL-INTROSPECT offers improved inspection of backtraces to the point

that local variables may be inspected in Lisp debug frames. Patches to

SLIME to use this feature are in the process of being merged into the

upstream repository. The OBJECTWEB system allows the user to disassemble

JVM bytecode via dependencies managed by Maven.

JSS now contains a syntax for accessing Java static and member fields.

For declaring dependencies on Java artifacts ABCL-ASDF, we have added

an experimental syntax to address JRE/JDK artifacts via the ASDF:JDK-JAR

class, as well as the ability to more finely control Maven dependencies

with the ASDF:MVN-MODULE class.

A complete list of [changes][] may be viewed in the source repository.


Binaries for this release may either be downloaded directly from,, retrieved from the distributed Maven

POM graph, or run from Docker via

        docker run -it easye/abcl:1.5.0

Many thanks to all who have contributed to nurturing the Bear's

execution of conforming ANSI Common Lisp on the Java Virtual Machine.

is nothing to compare to it now."
