Technical question about the Java Dependency Analysis Tool

[Staffan Larsen]

Hi Richard,

I think a better list for this question is either core-libs-dev@ or jigsaw-dev at .

Thanks

Consider a graph G constructed from the JDeps output, with the nodes represented by classes and the edges represented by vertices.  My question is, if a specific JAR file in the directory (call it A.jar) can compile using OpenJDK with the other JAR files in the directory designated as dependencies, then does there always exist at least one subgraph G’ of G that corresponds to the dependency relationships that would be actually used by a Java compiler to compile that JAR file? If the answer is “yes,” then I believe I should be able to recover that graph by starting with the set of classes in A.jar and constructing the subgraph G’ in a manner similar to that used by a depth-first search.
