After checking for it I found than invalid version of cgroup was detected.
This issue referenced to JDK-8239559

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create test project with Main-file
public static void main(String[] args) throws Exception {
ManagementFactory.getOperatingSystemMXBean();
}

2. Create file mountinfo with content
16 21 0:15 / /sys rw,nosuid,nodev,noexec,relatime - sysfs sysfs rw
17 21 0:3 / /proc rw,nosuid,nodev,noexec,relatime - proc proc rw
18 21 0:5 / /dev rw,relatime - devtmpfs udev rw,size=8206048k,nr_inodes=2051512,mode=755
19 18 0:12 / /dev/pts rw,nosuid,noexec,relatime - devpts devpts rw,gid=5,mode=620,ptmxmode=000
20 21 0:16 / /run rw,nosuid,noexec,relatime - tmpfs tmpfs rw,size=1643364k,mode=755
21 0 8:5 / / rw,relatime - ext4 /dev/disk/by-uuid/812d6452-9193-4e6d-a9fd-259061b14840 rw,errors=remount-ro,data=ordered
23 16 0:17 / /sys/fs/cgroup rw,relatime - tmpfs none rw,size=4k,mode=755
24 16 0:18 / /sys/fs/fuse/connections rw,relatime - fusectl none rw
25 16 0:6 / /sys/kernel/debug rw,relatime - debugfs none rw
26 16 0:10 / /sys/kernel/security rw,relatime - securityfs none rw
27 20 0:19 / /run/lock rw,nosuid,nodev,noexec,relatime - tmpfs none rw,size=5120k
28 20 0:20 / /run/shm rw,nosuid,nodev,relatime - tmpfs none rw
29 20 0:21 / /run/user rw,nosuid,nodev,noexec,relatime - tmpfs none rw,size=102400k,mode=755
30 16 0:22 / /sys/fs/pstore rw,relatime - pstore none rw
31 21 8:17 / /opt rw,relatime - ext4 /dev/sdb1 rw,data=ordered
33 23 0:24 / /sys/fs/cgroup/systemd rw,nosuid,nodev,noexec,relatime - cgroup systemd rw,name=systemd

3. create file cgroup with content
 #subsys_name hierarchy num_cgroups enabled
cpuset 0 1 1
cpu 0 1 1
cpuacct 0 1 1
memory 0 1 1
devices 0 1 1
freezer 0 1 1
net_cls 0 1 1
blkio 0 1 1
perf_event 0 1 1
net_prio 0 1 1
hugetlb 0 1 1

4. Setup 2 breakpoints:
4.1 jdk.internal.platform.CgroupSubsystemFactory:86
Map<String, CgroupInfo> infos = new HashMap<>();

4.2 jdk.internal.platform.cgroupv2.CgroupV2Subsystem:64
        String mountPath = null;

5. Run test project under debug.
When debugger stopped on breakpoint 4.1, replace variable values:
5.1 write file path of mountinfo, created on step 2 to variable
String mountInfo - jdk.internal.platform.CgroupSubsystemFactory.determineType(String, String)

5.2 write file path of cgroup, created on step 3 to variable
String cgroups - jdk.internal.platform.CgroupSubsystemFactory.determineType(String, String)

6. Continue program execution. It will stopped on second break point.

7. Press 2-3 times Step-Into until you will enter to java.nio.file.Paths:69

8. Replace variable value:
write file path of mountinfo, created on step 2 to variable
String first - java.nio.file.Paths.get(String first, String... more)

9. Continue program execution.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Program executed successfully.
ACTUAL -
Raised exception with stack trace
