[JDK 11] RFR: 8195096: Exception printed on console with custom LogManager on starting Apache Tomcat

[Daniel Fuchs]

Hi Mark,

Would it be possible for you to call super.getProperty()
when you want to see the 'raw' value, and
this.getProperty() when you want to see the 'corrected'
value?

best regards,
