Hi @muralicbe1983,
There is an issue with the BouncyCastle library in version 2.1.
Some workarounds are suggested in the discussion on bcgit/bc-java#1987.
You can also try setting the org.bouncycastle.native.loader.install_dir property to a directory other than `/tmp.

Alternatively, you can replace files from the opendj/libs directory with 2.0.x versions
org.bouncycastle.bc-fips.jar -> https://repo1.maven.org/maven2/org/bouncycastle/bc-fips/2.0.1/bc-fips-2.0.1.jar
org.bouncycastle.bctls-fips.jar -> https://repo1.maven.org/maven2/org/bouncycastle/bctls-fips/2.0.22/bctls-fips-2.0.22.jar
org.bouncycastle.bcutil-fips.jar -> https://repo1.maven.org/maven2/org/bouncycastle/bcutil-fips/2.0.5/bcutil-fips-2.0.5.jar
