Description Mike Millson 2018-12-14 20:59:16 UTC 
Description of problem:
Installing OpenJDK11 broke javac alternative.

Version-Release number of selected component (if applicable):
java-11-openjdk-headless-11.0.1.13-3.el7_6.x86_64
java-11-openjdk-11.0.1.13-3.el7_6.x86_64
java-11-openjdk-devel-11.0.1.13-3.el7_6.x86_64


Steps to Reproduce:
1. yum install java-11*
2. alternatives --config javac

Actual results:
# alternatives --config javac
failed to read link /usr/bin/javac: No such file or directory

Expected results:
Should see the menu to select the javac version.

Additional info:
I can manually create the link (have to run command 2x):
# alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-11-openjdk-11.0.1.13-3.el7_6.x86_64/bin/javac 180191
failed to read link /usr/bin/javac: No such file or directory
# alternatives --install /usr/bin/javac javac /usr/lib/jvm/java-11-openjdk-11.0.1.13-3.el7_6.x86_64/bin/javac 180191

Then can successfully run alternatives:

# alternatives --config javac

There are 4 programs which provide 'javac'.

Acording to:

*  3           /usr/java/jdk-11.0.1/bin/javac

It is clear that you have installed oracle's RPMS. Oracle's ROMS are known tobe not compatible wiht anything reasonable on this planet.
You have deliberately crippled your system. There is no way how to help you.
