> When instantiating {{ClassPath}} with {{{}ClassPath.getClassPath(){}}}, a {{UnsupportOperationException}} is thrown:
> {code:java}
> java.lang.UnsupportedOperationException
>     at java.base/jdk.internal.jrtfs.JrtFileSystem.close(JrtFileSystem.java:104)
>     at org.apache.bcel.util.ModularRuntimeImage.close(ModularRuntimeImage.java:83)
>     at org.apache.bcel.util.ClassPath$JrtModules.close(ClassPath.java:373)
>     at org.apache.bcel.util.ClassPath.close(ClassPath.java:576)
>     at TestBCEL.testClose(TestBCEL.java:35){code}
>  
> The following test-case can be used to reproduce this:
>  
> {code:java}
>     @Test
>     void testClose() throws IOException {
>         try (ClassPath cp = new ClassPath(ClassPath.getClassPath())) {
>             assertNotNull(cp);
>         }
>     } {code}
>  
> It seems some Java filesystems will throw this, maybe the exception needs to be caught and ignored in {{{}ClassPath$JrtModules.close(){}}}.
