What's the best way to go about debugging a failure with a Java
application using the Linux JDK provided by Oracle? The application in
question uses the gradle wrapper (i.e. gradlew) to run, but throws an
java.io.IOException error ("Too many levels of symbolic links"). Note
that this runs fine on Ubuntu so the assumption is the error is
related to some interaction with the Linux emulation. The JDK comes
from an RPM provided by Oracle and was installed using the rpm2cpio
method shown in the Handbook. Running JEdit with the Oracle JDK works
without error. TIA.
