Java version check

[daynefiler]

I was running into issues building the hg38/ucsc database under the following Java version:

openjdk version "1.8.0_192"
OpenJDK Runtime Environment (Zulu 8.33.0.1-linux64) (build 1.8.0_192-b01)
OpenJDK 64-Bit Server VM (Zulu 8.33.0.1-linux64) (build 25.192-b01, mixed mode)

Creating a separate conda environment where I did not have frozen package constraints everything worked. It would be really helpful for Jannovar to check the Java version and give at least a warning if not correct. I was receiving totally cryptic, unhelpful Java errors about garbage collection.

A note about the Java version would have gotten me to a working solution much sooner.

Thank you for the hint. I think we can integrate something like a java version check but I think we will do this only in the command line interface

@daynefiler Could you define "issues"?

[daynefiler]

Sorry — by “issues” I mean I was getting long uninformative error messages.

@daynefiler Hm, it's been a long time but can you reproduce them?
