> Log4J JUL is attempting to _MessageFormat_ a String passed by _*java.util.logging*_.Logger.info(java.util.function._Supplier_<*String*>)
and fails with java.lang._*IllegalArgumentException*_ when the String contains *_{ }_*.
> In the following example, line #2 will throw an _*IllegalArgumentException*_:
> {code:java}// writing the configuration file on the fly for the purpose of this demo
only
> try (java.io.PrintStream p = new java.io.PrintStream("./log4j-jul-test.xml")) {
>     p.println("<Configuration/>");
> }
> // specifying the java.util.logging.LogManager implementation
> System.setProperty("java.util.logging.manager", "org.apache.logging.log4j.jul.LogManager");
> System.setProperty("log4j.configurationFile", "log4j-jul-test.xml");
> java.util.logging.LogManager.getLogManager().getLogger("test").severe("This 1st {will}
be logged correctly by log4J");
> // output is: 11:15:40.492 [main] ERROR test - This 1st {will} be logged correctly by
log4J
> java.util.logging.LogManager.getLogManager().getLogger("test").severe(() -> "This
2nd {will not} be logged correctly by log4J");
> // output is: 2015-10-10 11:15:40,523 main ERROR An exception occurred processing Appender
Console java.lang.IllegalArgumentException: can't parse argument number: will not
