[GitHub] [accumulo] reggert opened a new issue #1401: `ShowTrace` servlet is

reggert opened a new issue #1401: `ShowTrace` servlet is unusable
URL: https://github.com/apache/accumulo/issues/1401
The fix for ACCUMULO-4660, 6f187823e4309ed79d6fa3f24b049731126f5263 , introduced a regression that makes it impossible to view traces via the Accumulo Monitor.
Specifically, `Basic.getStringParameter` was modified to strip out non-alphabetic characters from query parameters. Given that trace ids are hexadecimal strings, this causes all decimal digits to get stripped out. The `ShowTrace` servlet then behaves _very_ strangely as a result, as it ends up scanning the wrong range, which apparently returns entries that are not encoded spans, but tries to interpret them as such.
