During attach, if the .java_pid file is not secure we currently say "well-known file is not secure". This can be enhanced to say _why_ the file is not considered secure.
bug: https://bugs.openjdk.java.net/browse/JDK-8074812 webrev: http://cr.openjdk.java.net/~sla/8074812/webrev.00/ Note that it is safe to call JNU_ReleaseStringPlatformChars after the calls to JNU_ThrowIOException since the latter don’t actually change the control flow. Thanks, /Staffan
