Currently, JDK parameters are supported internally in the DBLE source code： SystemProperty.java

As mentioned in JDK link，java.specification.version updated to java.specification.maintenance.version in higher JDK versions

The java.specification.maintenance.versionJDK param is not currently supported in DBLE，so startup failed.

You can bypass the JDK link, mentioned in the JDK version, and start the DBLE successfully.
