I've been seeing some intermittent test failures where the
failure message is:

Exception: java.lang.RuntimeException: 'sharing' missing from stdout/stderr

This particular failure happened with this test:

runtime/AppCDS/RewriteBytecodesTest.java

Here is a more detailed snippet from the .jtr file:

----------System.err:(24/1207)----------
 stdout: [Error occurred during initialization of VM
Unable to use shared archive.
];
 stderr: [An error has occurred while processing the shared archive file.
Unable to map OptionalData shared space at required address.
]
 exitValue = 1
