#4079 jEdit.exe doens't work with OpenJDK

[ErroneousBee]

I have "AdoptOpenJDK 1.8.0_202" installed:
c:\Program Files\jEdit>java -version
openjdk version "1.8.0_202"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_202-b08)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.202-b08, mixed mode)

Running the jEdit 5.5.0 Installer pops up a message "This application requires a Java Runtime Environment 1.8.0"

Installation completes, but starting jEdit with jEdit.exe pops up the same message, aborts startup, and navigates my browser to the Oracle java.com website.

The jEdit background task suffers the same issue.

Launching jEdit from the command prompt java -jar jedit.jar works normally.

Oracle have recently changed the Java license, potentially charging for java 11, and many enterprises are moving to AdoptOpenJDK on windows to avoid licensing issues.

Please can:

1. jEdit.exe support OpenJDK 1.8 and later.
2. jEdit installer support OpenJDK 1.8 and later.
3. jEdit background task support OpenJDK 1.8 and later.
4. jEdit.exe either warn instead of fail, or omit the version test, perhaps via switches.
5. jEdit.exe not open any web pages, this is obnoxious behaviour.
6. jEdit installer consider pointing at the OpenJDK website.

You can try the new EXE launcher that I uploaded to https://sourceforge.net/p/jedit/bugs/4084/#a987
