Giovanni Matteo Fumarola commented on HADOOP-16219:
---------------------------------------------------

Thanks [~stevel@apache.org] .
Can you take a look of TestProcfsBasedProcessTree ?
{code:java}
memoryMappingList.add(constructMemoryMappingInfo(
	"7f56c177c000-7f56c177d000 "
	+ "rw-p 00010000 08:02 40371558 "
	+ "/grid/0/jdk1.7.0_25/jre/lib/amd64/libnio.so",
	// Format: size, rss, pss, shared_clean, shared_dirty, private_clean
	// private_dirty, referenced, anon, anon-huge-pages, swap,
	// kernel_page_size, mmu_page_size
	new String[] {"4", "4", "25", "4", "25", "15", "10", "4", "10", "0",
	"0", "4", "4"}));
{code}
I do not know if this change breaks the test.

> Java 7 is long EOL; having branch-2 require it is simply making the release process a
pain (we aren't building, testing, or releasing on java 7 JVMs any more, are we?). 
> Staying on java 7 complicates backporting, JAR updates for CVEs (hello Guava!) &c
are becoming impossible.
> Proposed: increment javac.version = 1.8
