Reproducible: Sometimes

Steps to Reproduce:
I test it in four computers, two are win7, the other two are winxp
1. create a c project, select makefile project
2. enable generate makefiles automatically
3. create a c file, then bulid the project
4. there will be three makefiles(Makefile sources.mk and subdir.mk) in the folder whose name is "Default"
5. open one of the thress files, than delete it, thress computers failed(include the two win7 computers), only one winxp success.
6. I look for the cdt source code, and maybe this is the problem: org.eclipse.cdt.make.internal.core.makefile.gnu.protected void parse( URI fileURI, MakefileReader reader )  throws IOException, this method did not close the reader, if I close it by reader.close(), the problem dispear.
