Sub Tasks

Description
When compiling using the useJavaUtilZip=true system option (that disables caching of the zip file indices in memory), the 6u25 javac crashes:
$ ./jdk1.6.0_25/bin/javac -J-DuseJavaUtilZip=true Test.java
error: error reading /tmp/jdk1.6.0_25/jre/lib/sunrsasign.jar; error in opening zip file
1 error

The javac version is:
$ ./jdk1.6.0_25/bin/javac -fullversion
javac full version "1.6.0_25-b05"

NetBeans is using this system option to prevent leaking memory through the zip file index cache: when a project is built inside NetBeans, the javac is run in the same VM to speed-up the building of small projects.

Comments
EVALUATION

This problem exists on Linux and Solaris. On Windows new ZipFile(...) does throw a FileNotFoundException.

SUGGESTED FIX

The fix is the same as shown in 6625520:
            } catch (IOException ex) {
>>>>>>>>>>>	if (zipFileName.exists())
                	log.error("error.reading.file", zipFileName, ex.getLocalizedMessage());
                archive = new MissingArchive(zipFileName);
            }

EVALUATION

As Jon pointed out in the comment, the problem is the openArchive method in DefaultFileManager.java.  It does this:
            try {
                 :
                if (!useZipFileIndex) {
                    zdir = new ZipFile(zipFileName);
                }
                 :
            } catch (FileNotFoundException ex) {
                archive = new MissingArchive(zipFileName);
            } catch (IOException ex) {
                log.error("error.reading.file", zipFileName, ex.getLocalizedMessage());
                archive = new MissingArchive(zipFileName);
            }

The problem is that new ZipFile(...) doesn't throw a FileNotFoundException if the file does not exist, instead, it throws a java.util.zip.ZipException, so that the log.error is executed.
