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

             Summary: Used Thread.getContextClassLoader() classloader for P2P
                 Key: IGNITE-3454
                 URL: https://issues.apache.org/jira/browse/IGNITE-3454
             Project: Ignite
          Issue Type: Bug

    Affects Versions: 1.6
            Reporter: Nikolay Tikhonov
             Fix For: 1.7


{{GridClassLoaderCache#detectClassLoader}} tries to load class by {{Thread.getContextClassLoader()}}
when it possible. In some cases it to lead to errors in cache operations:

Suppressed: class org.apache.ignite.IgniteCheckedException: Encountered incompatible class
loaders for cache [class1=[C, class2=org.apache.ignite.internal.processors.cache.distributed.dht.preloader.GridDhtPartitionFullMap]
