Steps to Reproduce: * make sure you only have the IBM jvm installed and it is listed as an installed JRE * import a java project from cvs At this point Eclipse tries to compile the project but fails with this message: The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project To fix this, right click on the project -> Properties -> Java Build Path -> Libraries tab -> Add External JARs ... -> select core.jar I've seen this both on x386 and on ia64 with Java projects and plugin projects.
Java packages installed on ia64: % rpm -qa | grep java-1.4.2 java-1.4.2-ibm-devel-1.4.2.0-1jpp_13rh java-1.4.2-ibm-src-1.4.2.0-1jpp_13rh java-1.4.2-ibm-1.4.2.0-1jpp_13rh java-1.4.2-ibm-demo-1.4.2.0-1jpp_13rh %
T've noticed that this happens for other jars in the JRE as well. The attachments below show the JRE System Libraries for both RHDS and eclipse from eclipse.org on the same machine with the same project. Notice that the eclipse.org version has a more complete JRE System Library.
Created attachment 107209 [details] eclipse.org JRE System Library
Created attachment 107210 [details] RHDS JRE System Library
Closing bug as we are no longer working on RHDS 2.0.
