Description
C2 could crash with assertion

#  Internal Error (/tmp/jprt/P1/232656.amurillo/s/src/share/vm/opto/escape.cpp:1059), pid=29266, tid=17
#  assert(false) failed: infinite EA connection graph build (61.458490 sec, 3 iterations) with 6320 nodes and worklist size 981

which indicates that C2 was not able finish work in time (60 secs)
However it is very possbile situation during stress testing. 

The real issue is that each person who see this failure first time could think that it is VM issues and file CR.

This crash cause failures of bigapps in Nightly, PIT & Promotion testing. We could not pass KS 7 days stress testing. All of this broke relase critteria. So I'm raising priority of this issue to P2.
