Major bug fix
- Load EnhancementProviders upon VariableDS instantiation by @lesserwhirls in #1478
This bug was introduced during the development of 5.6.1 (may be present in 5.6.1-SNAPSHOTs), and is present in releases v5.7.0 up to v5.9.1. This bug triggers a runtime error in a critical part of the codebase (VariableDS) in multithreaded environments. Here is an example of a stacktrace that is generated when the bug is triggered:
java.util.NoSuchElementException

Minimum Java version for netCDF-Java
Currently, the netCDF-Java project targets version 8 of the JVM. We are looking to get a feel for the minimum version required by the community, as support for Java 8 begins to dwindle for 3rd party dependencies that the project relies upon. Please consider participating in our GitHub poll. Thank you to those who have voted!
