java.util.concurrent.RejectedExecutionException

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • I had to write a tool that imports a batch of users into LDAP using the REST API. When executing this under Linux, it takes ~17 s to import 500 users. Under Windows, I was forced to put a 3.5 s sleep interval between the HTTP POST-s (which were consecutive) in order to avoid getting a DOS. This rounded the overall time to ~30 minutes for the same import of 500 users. After looking into the logs, I saw this mail-related exception being thrown: {code} 2013-11-08 14:00:24 INFO [qtp30859930-232] admin org.sonatype.security.model.source.FileModelConfigurationSource - Saving security configuration to: C:\java\nexus\nexus-oss\nexus-2.6.4-02\..\sonatype-work\nexus\conf\security.xml 2013-11-08 14:00:24 INFO [qtp30859930-232] admin org.sonatype.micromailer.imp.DefaultEMailer -
