netcdf-java 5.5.4 bugfix release?

[srstsavage]

Hi all,

Is it possible to get a 5.5.4 bugfix release in the near future? When using 5.5.3 we're hitting the following in ERDDAP on a complex ncml unit test:

java.lang.NullPointerException: Cannot invoke "String.contains(java.lang.CharSequence)" because "location" is null

This has been fixed by this commit since Oct 2022:

19f9476

specifically this line (the location null check in MFileZip.canProvide):

19f9476#diff-05b863736a1a2b21b57d0a498f731991e82c8b824dc2235d54f3f9d5f257eb80R200

but isn't yet included in any release.

Thanks!

We are currently working on the release and hope to have it out soon. We are working on one more fix that we want included so can't give a concrete timeline for it.
