JDK 9 RFR of JDK-8168499: Workaround intermittent failures of IntersectionTargetTypeTest.java

[Maurizio Cimadamore]

Hi,
the fix should address the immediate problem, but I'm not sure that 
memory is the culprit here. I've been able to run all tests in 
test/tools/javac/lambda (512 tests including several combo ones) using a 
shared VM and only 64M of heap, which is way less than the default used 
in a typical test run. To profile the test run I passed the -verbose:gc 
option to the vm used by jtreg using the -vmoption and noted no 
significant leak during the execution of tests in this folder. So, while 
I believe that this tests ends up often with an intermittent failure, I 
haven't been able to find evidence of a leak.
