Description PeteSL 2016-07-24 11:16:22 UTC

Build: NetBeans IDE 8.1 (Build 201510222201)
VM: Java HotSpot(TM) 64-Bit Server VM, 25.102-b14, Java(TM) SE Runtime Environment, 1.8.0_102-b14
OS: Windows 10

User Comments:
GUEST: ????

GUEST: I've opened NetBeans 8.1 on Linux x86_64 and, when it's finished to load all the projects, NetBeans's sent me notification of this exception.
Then the IDE hasn't found errors in sources code.

GUEST: Trying to extend one class from another

GUEST: Same as before

PeteSL: ciProperties extends java.util.Properties.  I believe the issue was when I changed get and put from public to private to hide them.

GUEST: Syntax errors in some files in the project aren't detected by the IDE

This did occur when I tried to hide get and put by making them private.  While this is an illegal operation, it should be flagged as an error in the UI, not causing an exception without noting why.
