Java agent invalid_argument unexpected EOF

#### Describe the bug
Hi, I'm sending profiles from a ARM64 based java service to a Pyroscope distributor.

My Java agent config
```
public class PyroscopeProfiler {
protected final FlagsConfig flags;
protected final String serviceName;
protected final String PYROSCOPE_BETA_URL =
"http://pyroscope-distributor.northwest.service.envoy:10080";

public PyroscopeProfiler(ServerBaseConfig serverBaseConfig, FlagsConfig flags) {
this.flags = flags;
this.serviceName = serverBaseConfig.getServiceName();
}

/** Start the profiler */
public void start() {
PyroscopeAgent.start(
new Config.Builder()
.setApplicationName(serviceName)
.setProfilingEvent(EventType.ITIMER)
.setFormat(Format.JFR)
.setServerAddress(PYROSCOPE_BETA_URL)
.setProfilingAlloc("512k")
.setProfilingInterval(Duration.ofMillis(10))
.setUploadInterval(Duration.ofSeconds(30))
.build());
}

/** Stop the profiler */
public void stop() {
PyroscopeAgent.stop();
}
}
```

Distributor error
```
"{\\\"code\\\":\\\"invalid_argument\\\",\\\"message\\\":\\\"unexpected EOF\\\"}\\n\"
```
Distributor config should all be default.

JDK version: 11
Java agent version: 0.18.0

#### To Reproduce
Steps to reproduce the behavior:

1. Start Pyroscope
2. Start client
3. Check logs in Pyroscope distributor

#### Expected behavior

Profiles should correctly distributed

#### Environment

- Infrastructure: Kubernetes
- Deployment tool: Internal tool

#### Additional Context
The requests does go through internal envoy proxy, I'm not sure if it affects the request payload.
