[SPARK-7756] CORE RDDOperationScope fix for IBM Java
IBM Java has an extra method when we do getStackTrace(): this is
"getStackTraceImpl", a native method. This causes two tests to fail within
"DStreamScopeSuite" when running with IBM Java. Instead of "map" or "filter"
being the method names found, "getStackTrace" is returned. This commit
addresses such an issue by using dropWhile. Given that our current method is
withScope, we look for the next method that isn't ours: we don't care about
methods that come before us in the stack trace: e.g. getStackTrace (regardless
of how many levels this might go).
IBM:
java.lang.Thread.getStackTraceImpl(Native Method)
java.lang.Thread.getStackTrace(Thread.java:1117)
org.apache.spark.rdd.RDDOperationScope$.withScope(RDDOperationScope.scala:104)
Oracle:
PRINTING STACKTRACE!!!
java.lang.Thread.getStackTrace(Thread.java:1552)
org.apache.spark.rdd.RDDOperationScope$.withScope(RDDOperationScope.scala:106)
I've tested this with Oracle and IBM Java, no side effects for other tests
introduced.
