Nios II Software Build Tools for Eclipse freezes from Java error

Question

I'm using Nios II Software Build Tools for Eclipse (Eclipse IDE for C/C++ Developers, Mars.2 Release (4.5.2), Build id: 20160218-0600) as part of Quartus Prime (Version 18.0.0, Build 614 04/24/2018 SJ Standard Edition).

Occasionally, the Nios II Eclipse IDE will just freeze, sometimes even when sitting idle. An Eclipse pop-up appears showing that a Java error occurred (see Nios_II_Software_Build_Tools_for_Eclipse_Java_error.png attachment). Is this a known issue? Is there a fix for it?

This workaround is for Platform Designer; however, my issue is with Nios II Software Build Tools for Eclipse. Additionally, this workaround is for Quartus Prime version 17.1 update 2 and earlier; however, I'm using Quartus Prime version 18.0.0. The Java error looks very different, but I looked into the workaround/fix anyway. No (good) luck. Anything else seem like a possible fit?

Have you tried another version of Quartus?
