Child process STDOUT is trimmed to 100 lines
Full child process STDOUT was saved to docker-stdout-44598.log
STDERR:
java.lang.RuntimeException: assertTrue: expected true, was false

The test output shows that the two java processes open the '/tmp/hsperfdata_root/1' file normally one after another, seems that the second java process start slowly.
