Description
On a test on a network connection which is clearly overloaded (parallel D/L of hadoop 3.1 JARS, 8 test threads active), got an exception
[ERROR] testMetricsOnBigFileCreateRead(org.apache.hadoop.fs.azure.metrics.ITestAzureFileSystemInstrumentation) Time elapsed: 71.585 s <<< ERROR! java.lang.IllegalArgumentException: Self-suppression not permitted at java.lang.Throwable.addSuppressed(Throwable.java:1043) at java.io.FilterOutputStream.close(FilterOutputStream.java:159) at org.apache.hadoop.fs.azure.NativeAzureFileSystem$NativeAzureFsOutputStream.close(NativeAzureFileSystem.java:1058)
This seems to imply that an exception was called with initcause==self. I don't see how the codepath would permit that though
