How to Execute OpenJDK Debugging Package

Question

I need OpenJDK's build that provides symbols for debugging in RedHat Linux Server 8.2. I had installed OpenJDK 1.8.0 252-* (latest) with:

yum install java-1.8.0-openjdk-devel

However, afterward I realize that I need a package that has been built with debugging enabled and also I was interested in a very specific version (242-*), so I downloaded it directly from RedHat Acces site ( this link ).

After installing it with rpm ( rpm -ivh java-1.8.0..... ), and chmod ing everything to 774, when I navigate to java directories, I don't seem to be able to execute java (or in this case java.debug ):

[root@localhost lib]# /usr/lib/debug/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b07-1.el6_10.x86_64-debug/bin/javac.debug -version
-bash: /usr/lib/debug/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b07-1.el6_10.x86_64-debug/bin/javac.debug: No such file or directory
[root@localhost lib]# /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el8_1.x86_64/bin/java -version
openjdk version "1.8.0_252"
OpenJDK Runtime Environment (build 1.8.0_252-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)

Am I missing something?

Answer 1

java-1.8.0-openjdk-debuginfo is a complementary package that provides debug symbols for OpenJDK binaries. This package is not self-sufficient; it does not contain executable binaries.

In order to use OpenJDK with debug symbols, you need to install both java-1.8.0-openjdk and the corresponding java-1.8.0-openjdk-debuginfo package of the same version.
