Hi, I've been exploring the new helpful NPE feature a bit.
It's a very welcomed improvement, but I noticed one potential usability issue in conjunction with the single source file mode (JEP 330): as debug info is missing in that case, e.g. local variables are rendered as "<local1>" in the exception message. Single source file mode also doesn't let me specify the "-g:vars" option I could use with javac for adding the debugging info. Perhaps single source file mode should add debug information by default to prevent this issue? Thanks, --Gunnar
