Description
Carlo Luib-Finetti
Would you have detailed steps to reproduce this problem ? There is not enough information in this bug report for us to understand the problem. Well, I didn't find a way to reproduce this bug. It only shows occasionally. Sometimes it shows up when I restart Eclipse, sometimes it is when closing one project and open another. I do switch projects about 10 times a day and restart Eclipse maybe 2 or 3 times a day; the erronoues behaviour manifests itself 2 or 3 times a week. *** Bug 185809 has been marked as a duplicate of this bug. *** If unable to find steps to reproduce, could you please enable some tracing as follows to help us understand what's going on ? 1. Create a .options file with the following content: # Turn on debug tracing for org.eclipse.jdt.core plugin org.eclipse.jdt.core/debug=true # Reports classpath variable initialization, and classpath container resolution org.eclipse.jdt.core/debug/cpresolution=true 2. Start eclipse with the following command: eclipse.exe -debug <path to your .options file> -vm <path to java.exe> e.g. eclipse.exe -debug c:\temp\.options -vm c:\jdk1.5.0\bin\java.exe => this should open a DOS console 3. Ensure that the DOS console buffer size is as big as possible (Properties > Layout > Screen Buffer Size > set width and height to 9999) 4. When the problem occurs, copy/paste the content of the DOS console into a file, and attach the file to this bug I wonder if this is a duplicate of bug 154984 ? Doesn't seem to be the case since it happens with M6 and 154984 has been fixed for M6. I've also encountered this problem on eclipse 3.3. I had added new user library with some jars and after few restarts user library has just disappeared. I have other user libraries defined and they behave ok. Only this one user library always disappear. My friend also complain about disappearing user libraries. (In reply to comment #7) > I've also encountered this problem on eclipse 3.3.

When I am running eclipse on java 1.5.0_12 few of my user libraries are unavailable (invisible), but when Im running eclipse on java 1.6.0_02 libraries are visible. Created attachment 76284 [details]

Comment to Logs: I have defined 9 user libraries. On java 5 I can see only 4 user libraries: - Axis1.4 - TMobileRAN - spring - hibernate_anotations On java 6 I can see all 9 user libraries. Thanks for the feedback Piotr. The trace from comment 10 shows that some user libraries are not initialized when they should. To further investigate, I improved the tracing again. Could you please replace your existing org.eclipse.jdt.core.*.jar (in the plugins directory) with the one posted at http://www.eclipse.org/jdt/core/r3.3/index.php#UPDATES ? Then please attach the new trace you get to this bug report. Thanks. Created attachment 76306 [details]
Extended Eclipse log when running on java 1.5
I attached log from new jdt (extended logs).
This time 3 user libraries are not visible:
- hibernate_core
- hibernateCore
- TestHibernateCore
These libraries contains exactly the same jars.
Thanks again. Now can you please attach ./metadata/.plugins/org.eclipse.core.runtime/.settings/org.eclipse.jdt.core.prefs to this bug ? Created attachment 76312 [details]
jdt preferences
Here it is.
I have rewritten the user library manager to make it simpler and thus avoiding a potential concurrency problem. Could you please try the patch at http://www.eclipse.org/jdt/core/patches/org.eclipse.jdt.core_3.3.1.z20070821-1711.jar and let me know if this fixes the problem ? Thanks.
