lhotari opened a new pull request #13435:
URL: https://github.com/apache/pulsar/pull/13435


   ### Motivation
   
   When running pulsar-admin and connecting to a broker with TLS, the first two 
lines of output in standard output are warnings from Netty / BoringSSL:
   ```
   17:15:47.460 [main] INFO  
io.netty.handler.ssl.ReferenceCountedOpenSslContext - BoringSSL doesn't allow 
to enable or disable TLSv1.3 ciphers explicitly. Provided TLSv1.3 ciphers: 
'TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384',
 default TLSv1.3 ciphers that will be used: 
'TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256'.
   17:15:47.814 [main] INFO  
io.netty.handler.ssl.ReferenceCountedOpenSslContext - BoringSSL doesn't allow 
to enable or disable TLSv1.3 ciphers explicitly. Provided TLSv1.3 ciphers: 
'TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384',
 default TLSv1.3 ciphers that will be used: 
'TLS_AES_128_GCM_SHA256:TLS_AES_256_GCM_SHA384:TLS_CHACHA20_POLY1305_SHA256'.
   ```
   This is annoying since it garbles the output.
   
   ### Modifications
   
   Don't call 
`sslEngine.setEnabledCipherSuites(sslEngine.getSupportedCipherSuites())` at all 
since it is useless. That's what causes the issue.
