Is this the Java8 equivalent of java.lang.OutOfMemoryError: PermGen space error? And is the proposed solution still the same, i.e. It is easily solved by adding more memory to the PermGen (something our CloudOps team can do for you) or by replacing some of the Java libraries by smaller ones (if they exist, that is)?
Based on my brief reading: yes. Add more Metaspace or use less/smaller Java libraries.
