RFR [9] 8156824: com.sun.jndi.ldap.pool.PoolCleaner should clear its context class loader

Another issue where an internal platform thread is unnecessarily retaining a reference to its creating thread’s context class loader. In this case, it appears to be safe to use an InnocuousThread, which will have a null context class loader. http://cr.openjdk.java.net/~chegar/8156824/01/ https://bugs.openjdk.java.net/browse/JDK-8156824 It’s not clear to me why the construction was not always in a privileged block, maybe “modifyThread” was assumed. We now definitely need a privileged block as the context class loader is being set. -Chris.
