Using a newer, alternative Java should in general not be a problem with the 
netCDF-Java library.

As for Panoply, it mostly works just fine with alternative Java installs.

It can be problematic on Windows due to how Windows registry keys are handled 
and whether/how the alternative Javas try to work around that. The AdoptOpenJDK 
install offer does offer a work around for this. Other alternative Javas may 
not.

On macOS, there should be less fussing about. I have run Panoply on macOS using 
AdoptOpenJDK's Java 14 and it's 99%+ the same experience as Java 8 - 13. Some 
curiosities about the color theme of the file dialog window, but otherwise the 
same.

Running Panoply, IDV, ToolsUI, etc on Linux installs should encounter even less 
trouble.

    Hello Yuichiroさん

    The Java Virtual Machine (JVM) downloaded from AdoptOpenJDK should be close 
to identical to the Java shipped by Oracle. Panoply run well with OpenJDK 14 at 
least on my machine. I suggest:

    * Download a JVM from https://adoptopenjdk.net/ 
<https://urldefense.proofpoint.com/v2/url?u=https-3A__adoptopenjdk.net_&d=DwMDaQ&c=ApwzowJNAKKw3xye91w7BE1XMRKi2LN9kiMk5Csz9Zk&r=ObgOyc0ZA16pUYS7QXU8zl-A-WUzVHPaNyUr1nNB0Qw&m=7StMaH2brZ7FxkskFHUtSNXSUBn1JkxHkybFk-O7cXU&s=fnwaBosmXE2ftsc0ItjTLM3-Qk2vOZzzmdLUqSNSLNg&e=>
 (the default setting proposed on that page is okay).
    * Unpack in any directory.
    * Open a terminal (command line)
    * Type the following command (replace "/path/to/java" by the path to the 
directory where OpenJDK has been unpacked). It should print "openjdk version …"

    /path/to/java/bin/java -version


    * Launch Panoply as below (replace "/path/to/panoply" by the path to the 
directory where Panoply is installed)

    /path/to/java/bin/java -jar /path/to/panoply/jars/Panoply.jar

    I have not tried Corretto and Zulu, but I guess it would work the same.
        Regards,
            Martin

    Dear all,

    I have used the application using netCDF-Java library.
    (e.g., https://www.giss.nasa.gov/tools/panoply/)

    However,

    - Final free version of Java for us is Java 8 Update 201(8u201) and
      Update 202(8u202). And it will be end of updates in Jan. 2019.
    - Java for us including recent versions released after Feb. 2019
      will be non-free.
    - I need to either transition to alternatives
      (AdoptOpenJDK, Corretto and Zulu) or purchase a Java SE Subscription.

    So, I want to know how you handled that.

    Best regards,
