Error with AutoReload

[willypow]

I'm getting an error when I update my extension class files:

Exception in thread "extensionReloader" java.lang.ClassFormatError: Truncated class file

Any idea why that would be?

a corrupt file, or missing a } would be my first guesses.

The extensions load fine when the server is restarted. The issue is only when auto-reloading.

Are you deploying just one file or multiple class files?
Also try reloading from the AdminTool, you shouldn't get that problem, if it is what I think it is...
If AdminTool is okay I will explain...

I can reload from the Admin tool. Oddly, the admin tool shows one of my java extensions as type Actionscript.

What is the issue?

Also, there are multiple class files. Some are not extensions.

Hi,

I can reload from the Admin tool. Oddly, the admin tool shows one of my java extensions as type Actionscript.

reloading from the Admin Tool should never fail.
Unfortunately the auto-reload can fail at times if the server realizes that new files were written and starts reloading while the files are still being transferred.

We'll try to better address this problem in a next release, but there is no perfect solution to this because there's no way to know how many files are being written. In fact the reloading is triggered when the server sees a change in the "last modified" date of the main extension file.

When there's many files being transferred or the transfer is slow (e.g. via FTP / HTTP) the prolem can arise.

Reloading from AdminTool does not incur in this issue for obvious reason: the developer first transfer the data then goes to the admin tool and hits the Reload button, acting as a mean of synchronization

That makes perfect sense and explains why this doesn't happen in our local environment. We will use the Admin tool.
