[Newbie question] Strange errors trying to build the JDK

[Zambonifofex]

Hello, everyone.

I am new to collaborating to the JDK, so sorry if this question is too
newbie‐ish.

I have recently been affected by a minor bug in the ‘java.desktop’
module on Linux. I figured I’d try to fix it by myself, so I followed
the steps in the “How to Contribute” page, the “Building” page, as
well as some more that I could find online.

The bug number is ‘7162479’. The bug is that it calling
‘setLocationByPlatform(true)’ on a ‘JFrame’ will not work if
‘setResizable(false)’ has been called on the same ‘JFrame’.

When I tried to build the JDK with ‘make images’, after getting a
couple errors related to the changes I made and fixing them, I started
to face a strange error that was not related to the changes I made at
all.

Here is the log I get when trying to run ‘make images’ currently, as
well as the output of ‘hg id’, if that’s of any help (where
‘/home/zambonifofex/jdk $’ is the prompt):

    /home/zambonifofex/jdk/ $ hg id

    Hint: Try searching the build log for the name of the first failed target.
    Hint: See doc/building.html#troubleshooting for assistance.

Any help would be appreciated. Thanks in advance.
