      After update of Jenkins from 2.8 to 2.48 nodes get stuck from time to time.
      Thread dump shows:

      In changelog we found that with Jenkins version 2.47 Groovy was updated to 2.4.8 "to address memory leak issue".

      Possibly this issue is related to

      https://issues.apache.org/jira/browse/GROOVY-8067: Possible deadlock when creating new ClassInfo entries in the cache

      which is in Groovy 2.4.8 and solved in 2.4.9
