Nearly every time I'm doing a complete rebuild of my java project the build fails with the following 
error: "A class file was not written. The project may be inconsistent, if so try refreshing this project and 
rebuilding it."  When I force Eclipse to recompile the concerned java file (by entering and deleting a 
blank and saving the file) the build either succeeds or the error occurs one or two times again for 
another file and I also have to recompile those files until the build finally succeeds.

Every time the error occurs another java file is concerned. So the error is not reproducible for a certain 
java file or even a certain package. The error does not occur if eclipse has to build a small number of 
files. It usually occurs when Eclipse has to build several thousand files (for example after cleaning the 
project) and after several hundred files have been successfully compiled.

Some additional information from the error log:

package names, the folder project_home is linked to another folder in the file system):
