I just started forked a JVM from a benchmark setup using something like
this:
List<String> command = new ArrayList<>();
command.add(
new File(new File(System.getProperty("java.home"), "bin"),
"java").getCanonicalPath());
command.add(
"-D" + DistributionConfig.GEMFIRE_PREFIX +
ConfigurationProperties.MCAST_PORT + "=0");
command.add(
"-D" + DistributionConfig.GEMFIRE_PREFIX +
ConfigurationProperties.LOCATORS + "\"\"");
command.add("-Dgemfire.cache-xml-file=" +
destServerXml.getAbsolutePath());
command.add("-cp");
command.add(System.getProperty("java.class.path"));
command.add(ServerLauncher.class.getName());
command.add(ServerLauncher.Command.START.getName());
command.add("server1");
command.add("--server-port=" + this.serverPort);
The resulting JVM has a bewildering reference to ExportLogsIntegrationTest
and LocatorStarterRule in its "main" thread. It's almost as if some of the
geode-core test code is somehow being found by the CommandManager scanning
done by gfsh and this is being triggered by creating the MemberMXBean in
the newly launched Server. I think ClasspathScanLoadHelper needs to exclude
classes from test sources, but since I'm running a class in src/jmh, I'm
not sure how to fix this?
