------------------------------------

             Summary: Test failures with Java 9 when using javax.imageio.spi.ServiceRegistry
                 Key: JCR-4179
                 URL: https://issues.apache.org/jira/browse/JCR-4179
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-jcr-client, jackrabbit-jcr-commons, jackrabbit-spi-commons
    Affects Versions: 2.15.5
         Environment: Java 9 b181
            Reporter: Robert Munteanu
            Assignee: Robert Munteanu
             Fix For: 2.15.6


When building with Java 9 there is at least one test failure due to using javax.imageio.spi.ServiceRegistry as a general-purpose service loader, which is not possible anymore with Java 9:

{noformat}
[ERROR] Tests run: 3, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.13 s <<< FAILURE! - in org.apache.jackrabbit.commons.JcrUtilsTest
[ERROR] testGetRepository(org.apache.jackrabbit.commons.JcrUtilsTest)  Time elapsed: 0.128 s  <<< ERROR!
java.lang.IllegalArgumentException: javax.jcr.RepositoryFactory is not an ImageIO SPI class
	at org.apache.jackrabbit.commons.JcrUtilsTest.testGetRepository(JcrUtilsTest.java:50){noformat}

We should move away from this ServiceRegistry and use {{java.util.ServiceLoader}} instead.
