There are quite a few of these. It might be useful to make a copy of whichever Java file is triggering the error, and then carefully simplify it down until you have a minimal example that will trigger the example.
For example, here are some similar javac errors I've reported in the past: https://issues.apache.org/jira/browse/NETBEANS-4384 https://issues.apache.org/jira/browse/NETBEANS-4296 https://issues.apache.org/jira/browse/NETBEANS-4180 https://issues.apache.org/jira/browse/NETBEANS-4179 https://issues.apache.org/jira/browse/NETBEANS-4095 (Your stack trace does not seem to be covered by any existing report, though--I searched JIRA for "Code.typecode" and found no results.) -- Eirik -----Original Message----- From: Scott Palmer <[email protected]> Sent: Saturday, June 6, 2020 2:44 PM To: Apache NetBeans <[email protected]> Subject: NPE in Java parsing Get this when the Ice starts up and opens my projects. I’m not sure what project is causing it. I am in the middle of porting some code from Go to Java and I have pasted Go code into Java source files, so there are tons of errors until I manually get to re-writing them. Still, I would expect the parser to handing syntax errors gracefully. Given that the NPE seems to be inside JDK code, I can say that this is a NB bug, but I bring it to your attention here so that someone more familiar with the java source parsing can perhaps pass on a report to the JDK folks.
