Bug 5093 Lost exported classpath entries
Build 205 1. Create new java project 2. Open build path properties 3. Check JRE_LIB so it is exported 4. Press OK 5. Open build path properties again Observe: JRE_LIB is not exported (but it is according to the .classpath) If you press OK without paying attention, you will loose the fact that JRE_LIB was exported.
