java.util.zip.ZipException while analyzing a class file

[eungjun-yi]

When I try to analyze a class file with findbugs GUI tool and MutabilityDetector4FindBugs plugin, findbugs popups a dialog box which describes an exception occurred as follows:

  Exception analyzing Test using detector org.mutabilitydetector.findbugs.MutabilityDetector4FindBugs
    java.lang.RuntimeException: java.util.zip.ZipException: error in opening zip file

      At edu.umd.cs.findbugs.gui2.AnalyzingDialog$AnalysisThread.run(AnalyzingDialog.java:260)

And also it produces log entries to console as follows:

5월 14, 2015 10:58:07 오전 org.mutabilitydetector.repackaged.com.google.classpath.JARClassPath loadEntries
경고: Failed to read Jar file /home/nori/mysrc/test/java/mutability/Test.class

Finally the result of the analyze does not include diagonastic reports about mutability.

It works well when analyzing a jar file.

Hi, thanks for the report. Will try to have a look over this weekend. I don't tend to use FindBugs on zip files, so haven't come across this issue before.
