Teams:

With this latest and greatest version of VStar, David cleared up several annoying bugs - mostly related to plug-ins and locale-sensitive number parsing. Thanks very much to VStar Team members Bikeman and Doug Welch for communicating the problems and sticking with it as solutions were tried, tested and tested again. The team spirit is alive and well with VStar!Please see the attached ChangeLog for more detailed information about the changes that were made in this version.

David also updated the plug-in documentation which I have included in "attachments" to this post. If you are interested in extending the capabilities of VStar even further, you are invited to try writing your own plug-ins using this document as a guide. Or you could try using one of the existing plug-ins which you can download from the SourceForge website here:

https://sourceforge.net/projects/vstar/files/vstar-plugins-2.9.zip/download

Simply unzip the .jar files you find there and place them in a folder called vstar_plugins which you must create in your home directory (for Mac or *nix users that will be $HOME or ~; in Windows it will be "C:\Documents and Settings\user"). One of the things we will be working on in the next few weeks is figuring out how best to organize and document these and make them readily available to VStar users. Ideas and thoughts on this subject would be most welcome.

Errors?

Hi all Thanks again to Sara for deploying version 2.9 to VStar while I slept. :) A couple of people have seen this kind of error on start-up with the latest release:

Exception in thread "AWT-EventQueue-0" java.lang.IncompatibleClassChangeError: Implementing class

at java.lang.ClassLoader.defineClass1(Native Method)

at java.lang.ClassLoader.defineClassCond(ClassLoader.java:632)

at java.lang.ClassLoader.defineClass(ClassLoader.java:616)

at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) ... If you see this kind of error (e.g. in a WebStart Java console or shell) or if VStar just doesn't start, I would suggest removing all jar files from the vstar_plugins directory (in your home directory for Linux, Mac OS X, or Documents and Settings for WinXP, or Users for Vista, ...) and restarting VStar. Also, for the FITS plug-ins, be sure to copy tamfits.jar to the vstar_plugin_libs (in home directory again). I have updated the zip file Sara refers to on SourceForge with tamfits.jar. As Sara commented, we will be working towards making plug-in installation easier. In general, if you are having any problem at all in running VStar, please don't hesitate to post a message here o if you prefer, email Sara or I.

Regards, David
