Seadas java problems (openjdk11 and oracle 12)

[cortivo]

Hi,
Last version of Seadas (7.5.3) does not open using java openjdk11 or oracle 12. I'm using Debian Buster.
Java 8 from oracle is no longer available to download publically.
Using Java openjdk11 when I try to open Seadas by comand line I get this error and Seadas start to open but close soon

[OB SeaDAS - knowles]

You can download java 8 here:
https://www.oracle.com/technetwork/java/javase/downloads/index.html

SeaDAS 7 does not support java versions later than java 8.

Debian does not provide non-free software, but there are efforts to provide supported free JDK options, mainly but not exclusively based on openJDK: Java is still free.   If your site policy requires current support,
IBM's Java might be a suitable replacement.   SeaDAS 7.5.3 does run under the IBM jre:
java -version
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build xx.xxx.xx.xx - pxa6480sr5fp40-20190807_01(SR5 FP40))
IBM J9 VM (build 2.9, JRE 1.8.0 Linux amd64-64-Bit Compressed References 20190802_424001 (JIT enabled, AOT enabled)
OpenJ9   - 106f6ce
OMR      - fe07f6f
IBM      - af2a365)
JCL - 20190712_01 based on Oracle jdk8u221-b11
 

ESA SNAP provides an Oracle Java runtime.   You can switch to the SNAP jre by editing the seadas script in the SeaDAS bin directory.
With SNAP installed in a user's home directory, the following change allows the jre to be shared between SNAP and SeaDAS-7:

$ diff seadas seadas-snapjre
4c4
< # INSTALL4J_JAVA_HOME_OVERRIDE=
---



> INSTALL4J_JAVA_HOME_OVERRIDE=$HOME/snap/jre
