CFR can't handle recent Oracle JDBC jars

[dan-blum]

CFR version

CFR 0.152

Compiler

javac 17.0.4.1

Description

When run on an OJDBC8 jar file - for example, ojdbc8-21.1.0.0.jar - CFR produces java.lang.NullPointerException: Cannot invoke "java.io.File.getCanonicalPath()" because the return value of "java.io.File.getParentFile()" is null org.benf.cfr.reader.state.ClassFileSourceImpl.addToRelativeClassPath(ClassFileSourceImpl.java:371) org.benf.cfr.reader.state.ClassFileSourceImpl.addJarContent(ClassFileSourceImpl.java:270) org.benf.cfr.reader.state.DCCommonState.explicitlyLoadJar(DCCommonState.java:141) org.benf.cfr.reader.Driver.doJar(Driver.java:127) org.benf.cfr.reader.CfrDriverImpl.analyse(CfrDriverImpl.java:76) org.benf.cfr.reader.Main.main(Main.java:54)

It's not an issue with my filesystem because it works fine on other jars (including older Oracle JDBC jars) in the same directory.

Had the same issue with another jar. Simply unjar the original jar into a new folder then rebuild it using "jar cvf ...", then use the new rebuilt jar file.
