Kato: A Java API for Post-Mortem JVM Diagnostics

Kato is a project undergoing incubation at The Apache Software Foundation.

Introduction

Kato is an Apache Incubator podling and JSR that exists to develop a standard Java API (JSR-326) designed to support the generation and consumption of post mortem or snapshot Java diagnostic artefacts.

Incubation at Apache

Apache Kato is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Incubator PMC.

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.

While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
