The changes for
 6280693: Mmap the whole jar files takes too much perceived footprint
have caused failures on Solaris when an interrupted thread uses the java.util.zip API.

The following program:
---------------------------------------------------------------
import java.util.zip.*;

public class InterruptibleZip {
    private static String rtJar() {
String bcp = System.getProperty("sun.boot.class.path");
for (String jar : bcp.split("[;:]"))
if (jar.endsWith("rt.jar"))
return jar;
throw new Error("Can't find rt.jar");
    }

    public static void main(String[] args) throws Exception {
ZipFile zf = new ZipFile(rtJar());
Thread.currentThread().interrupt();
ZipEntry ze = zf.getEntry("java/lang/Object.class");
System.out.println("interrupted="+Thread.interrupted());
System.out.println(ze.getName());
    }
}
---------------------------------------------------------------

results in

...b45/binaries/solaris-sparc/jre/lib/rt.jar: error reading zip file
Exception in thread "main" java.lang.NoClassDefFoundError: java/util/zip/ZipEntry
