Short of anything else:
* on the Linux box (it is four times slower than my current Windows laptop)
when the crash point
comes nearer the times between the last (appr. ten) JSP requests become
longer and longer, as if
the Rexx executions slow down from RexxInterpreter instance to
RexxInterpreter instance. (The
setup is a Java client using http requests to fetch the ooRexx-JSP from the
Tomcat 9 and Tomcat
10 server. The Tomcat servers have a taglib that allows ooRexx scripts to
be embedded and that
get run upon each request. The test JSP has a single Rexx script that
outputs text with the
result of .dateTime~new, cf. the JSP file below.)
* not sure whether this is relevant: .input, .output and .error get
redirected to Rexx objects
that forward to the Java Reader and Writers supplied by the Java scripting
framework (.stdin,
.stdout, .stderr remain untouched).

<h1>"Hello, world ..." (ooRexx)</h1>
*<s:script type="rexx">****say '<p style="background-color:
