The commit here tries to address an intermittent failure reported in https://bugs.openjdk.java.net/browse/JDK-8254267.

The `LogParameters` test case sets the log level to `ALL` for the `java.lang.String.class` and then attaches a handler to it. It then proceeds to write out a log message at `DEBUG` level and expects the log message to have been delivered to the handler.  This should all work fine and does work fine except for those intermittent failures.

Looking at the output attached in that JBS issue, there's this:

command: main LogParameters
reason: Assumed action based on file name: run main LogParameters
Mode: agentvm 

which states that the test is using `agentvm` mode, since the test itself doesn't specify a specific mode. For a test like this one which deals with log level management of `java.util.logging` infrastructure, in theory, there are chances that some other tests within the same JVM instance might impact the output and can potentially contribute to intermittent failures like this one.

The commit in this PR tries to address that issue by explicitly running the test in `othervm` mode.

P.S: Every once in a while my logins to JBS don't work and if I just wait for a few hours, things get sorted on its own. Today is one such occasion - successful login, but it still shows me as logged out and doesn't allow me to do anything. So I decided to directly create this PR instead of first commenting there.
