Launch Eclipse on a new workspace with IBM 1.4 VM specified in the command line. Create a new Java project. No JRE_LIB is added and there are two errors in the task list. Go to Window >Preferences > Java > Installed JREs. An error dialog is displayed and says "Installed JRE location no longer exists. JRE will be removed. Reason: JRE removed". Every time I try to add the 1.4 VM, I get the same message and I cannot install it.
Well, the problem is very simple: there is no rt.jar file under jre/lib. Instead, it appears the standard Java classes have been split up into 7 different jar files with names like core.jar, graphics.jar, security.jar, server.jar, etc. We should find out if this is how they (IBM) intend to ship this VM. If so, we will have to accommodate it, probably by creating a new VM install type.
A similar issue exists on Apple's MacOSX JRE.
Marking as duplicate of bug 22390. Edward, can you file a separate bug (against JDT/Debug) and list the details of how the MacOSX JRE classes are broken up (how many jars and their names)? Thanks. *** This bug has been marked as a duplicate of 22390 ***
