JavaRebel 1.2.1 & Spring Plugin 1.0-M2

We are very proud to present not one, but two simultaneous releases.

• JavaRebel release includes mostly fixes to the 1.2 branch, but also features installation instructions for the Spring Application Platform. The most notorious issues fixed were the ones causing Java 1.4 users a ExceptionInInitializerError on startup and IBM WebSphere users a StackOverflowError. If you were hit by those issues you should try again with this release. See changelog or download.


• The Spring plugin release includes fixes and performance improvements. The plugin will no longer rescan all XML files on every web request and the introduced delay should now be measured in milliseconds. A number of problems with Spring Security has been fixed and it should now work without any issues. See changelog or download.

JavaRebel is a JVM plugin (-javaagent) that enables to reload changes made to Java class files on-the-fly, saving developers the time that it takes to redeploy an application or perform a container restart. It is a generic solution that works for Java EE and Java standalone applications. See the demonstration screencast.
