We no longer use tools/java (scylladb/scylla-tools-java.git) for nodetool or cqlsh; only cassandra-stress. Since that is available in package form install that and excise the tools/java submodule from the source tree. pgo/ is adjusted to use the packaged cassandra-stress (and the cqlsh submodule). A few jmx references are dropped as well. Frozen toolchain regenerated.
