Failure to handle errors loading process-uuid file

XMLWordPrintable

      If standalone/data/kernel/process-uuid (for standalone mode) exists but is empty, startup fails with:

      java.util.NoSuchElementException: No value present
    at java.util.Optional.get(Optional.java:135)
    at org.jboss.as.controller.operations.common.ProcessEnvironment.obtainPr
ocessUUID(ProcessEnvironment.java:188)
    at org.jboss.as.server.ServerEnvironment.<init>(ServerEnvironment.java:632)

      If it exists but does not contain a valid UUID startup fails with the only slightly better:

       

      java.lang.IllegalArgumentException: Invalid UUID string:
    at java.util.UUID.fromString(UUID.java:194)                            
    at org.jboss.as.controller.operations.common.ProcessEnvironment.obtainProcessUUID(ProcessEnvironment.java:188)
    at org.jboss.as.server.ServerEnvironment.<init>(ServerEnvironment.java:632)

      These failure conditions should be handled more gracefully, ideally by ignoring the bad data and proceeding the same as if the file did not exist, but at the minimum with a more useful error message telling the user specifically what is wrong (that the problem is a corrupted standalone/data/kernel/process-uuid file).
