hotspot compiler test failed

[Liu Xin]

hi, Developers,

our CI detects a failure last night. The setup of test is like this. it's
suggestion from Kozlov.

make test TEST="jtreg:test/hotspot/jtreg/compiler"
JTREG="VERBOSE=nopass;VM_OPTIONS=-Xcomp -ea -esa -XX:CompileThreshold=100
-XX:-TieredCompilation"

There're two commits in that build.
