Which version of java are you using. Check you have tools.jar on the class path ?

HI,
We are migrating our application to JRE 11 from JRE 8. we are using 3.23.5 version of chronicle map. Application is shutting down while starting. Below is the error

Exception in thread "main" java.lang.AssertionError: java.lang.ClassNotFoundException: com.sun.tools.javac.api.JavacTool
at net.openhft.compiler.CompilerUtils.reset(CompilerUtils.java:64)

Based on my understanding, tools.jar is not present any more in jre 11. But chorincle map depends on JAvacTool which is from tools.jar. How should we mitigate this problem ?
Should i add tools.jar as part of the classpath in JRE 11 ( copied from JRE 8 ) ?
