Reproduce the error by refreshing Referenced Libraries, then inspect ProjectUtils.java at resolveGlobPath, groupGlobsByPrefix, and collectBinaries, followed by UpdateClasspathJob.java. Trace the null value shown in the stack trace and verify that refreshing the classpath no longer raises the reported NullPointerException.
