Description Matt R

Build Identifier: I20100608-0911

Clean Eclipse 3.6 install on 32-bit Ubuntu 10.04, JDK 1.6.0_18. After I install AJDT from the 3.6 AJDT update site, when I go to Window->Preferences->JDT weaving, weaving is disabled. I can enable it, and it is noted in the error log:

eclipse.buildId=I20100608-0911
java.version=1.6.0_18
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_GB
Framework arguments:  -showlocation
Command-line arguments:  -os linux -ws gtk -arch x86 -showlocation -console

Weaving service successfully ENABLED

Then when I restart, I get a "shutdown error" in the Error log:

After a restart, the weaving service is still disabled.

Reproducible: Always

Your error on shutdown is preventing Eclipse to save its state and so therefore Eclipse is not remembering that Weaving should be enabled on the next startup.  I have not seen this shutdown error stack trace before and it doesn't include any weaving or AJDT code, so it could possibly be from a different plugin (but it is not out of the question that this is somehow coming from our code).

Regardless, it is possible to force weaving to be enabled in a different way.  The full description is here:

http://wiki.eclipse.org/JDT_weaving_features

But, simply put, you can do this:

0. Shut down eclipse
1. Open the file eclipse/configuration/config.ini in your favorite text editor/
2. Find the line that starts with: 
   osgi.bundles= 
and add after the '=': 
  org.eclipse.equinox.weaving.aspectj@2\:start,
3. Make sure there is a line that looks like (and if it is not there, then add it):
   osgi.framework.extensions=org.eclipse.equinox.weaving.hook
4. Start eclipse

Weaving should be active now.  If for some reason that doesn't work, read the rest of the page I provided above.  Please let me know if this works for you, and I can help you more if it doesn't.

Any progress on this?

Sorry to take a while to get back to you on this. Setting config.ini by hand fixed the problem -- cheers. Also, I get the shutdown error even on a clean install of 3.6, so it's definitely not the fault of AJDT.

Thanks for getting back to me on this.  Glad that your problem is resolved.
