To avoid getting stuck due to  JDK-8305420, we need to remove the logging in CDSJDITest.java

https://github.com/openjdk/jdk/blob/aa762102e9328ca76663b56b3be6f6141b044744/test/jdk/com/sun/jdi/cds/CDSJDITest.java#L64

        // Args to the Main Class:
            // These argument all follow the above <testname> argument, and are
            // in fact passed to <testname>.main() as java arguments. <testname> will
            // pass them as JVM arguments to the debuggee process it creates.
            "-Xbootclasspath/a:" + appJar,
            "-XX:+UnlockDiagnosticVMOptions",
            "-Xlog:class+path=info", // <<<<<<<<<<<<<< HERE
            "-XX:SharedArchiveFile=./SharedArchiveFile.jsa",
            "-Xshare:on",
            "-showversion"

Three test cases are affected:

test/jdk/com/sun/jdi/cds/CDSBreakpointTest.java     
test/jdk/com/sun/jdi/cds/CDSFieldWatchpoints.java
test/jdk/com/sun/jdi/cds/CDSDeleteAllBkptsTest.java  

(Please see JDK-8305420 for the root cause).
