The attached file hotspot_crash_1007.tar.gz contains the following information:
- core file
- dbx stack and threads
- output of showrev and uname
- exact/full hotspot error
- JVM options/flags used
(a 2nd attached file hotspot_crash_1006.tar.gz contains similar info from a
similar crash)

Currently, we are procuring additional info from as follows, just to see
of the crash is happening due to JNI OR due to JIT compiled code:
- to compile libcom_att_sas_utilities_XMLcrypto.so native library
on Sol8 prod server, along with -g option as well, to avoid
dbx demangle warnings
- procure info from the following test runs on 2 different prod servers:
1. -client, with -Xcheck:jni and -client and -XX:+PrintCompilation
2. -server, with -XX:-UseTLAB, -XX:+PrintGCDetails
