Subject: Possibility to open SCL-modules from plug-in in JAR-file
X-Git-Url: https://gerrit.simantics.org/r/gitweb?a=commitdiff_plain;h=b591e7d001d39a73003edcdbe45457159b808815;p=simantics%2Fplatform.git

Possibility to open SCL-modules from plug-in in JAR-file

The real NPE problem was already fixed in c52bf8a8 by Hannu, but this
adds some SLF4J logging.

gitlab #77
