I am using this version for quite some time, Can you help me with the issue?

What did you set your EXTRA_JAVA_OPTS to?

Are you using 64-bit Java? Not supported by OH2 - mostly due to serial problems as it happens.

I have not set any extra opts.
Yes, it is 64bit version.
Trying with older version of java, will update you soon.

Issue is resolved after changing the the java version to 1.8.0_172,64-bit.
