Why warnings crashes openJDK-11 build?

I need to build following openJDK
git clone --depth 1 --branch jdk-11+28 https://github.com/openjdk/jdk.git
on aarm64 NAME="Simply Linux", VERSION="9.1 (Destiny)"
For that I run:
bash ./configure
make images > make.log
And it fails with following error (make.log)

Warning: No mercurial configuration present and no .src-rev

Error assigning variable in ODI 12.2.1.4: java code works in 12.2.1.3

There is a procedure with Java BeanShell technology that does the following:
**<#
String res="<?=p_valuexx?>";
#>**
Procedure returns lots of variables p_xxx (and one above including).
The next step in ODI does the variable assignment:
**<#=res#>**
this fails with the following error message:
oracle.odi.runtime.agent.exception.ExecutionEngineException: com.sunopsis.tools.core.exception.SnpsSimpleMessageException:
ODI-17517: Error during task interpretation.
Task: 5

The same code is working just fine in 12.2.1.3

It is a bug with OpenCV, so the solution is in two ways:
Open modules/java/generator/gen_java.py file and edit the line 1029 from
re_package = re.compile(r'^package +(.+);$')
to
re_package = re.compile(r'^package +(.+);')
Or just redownload the source and it is OK.

I suspect the issue is with your path.
/home/fcemtopall/Masaüstü/opencv-3.4.1/modules/java/generator/src/java/org/opencv/osgi/OpenCVNativeLoader.java.in

See this two U letters which are from another language. This might interpret a compilation issue when trying to generate JNI.
Try creating another directory under home such as /home/abc and compile from there.

Baksmali error for android odex file

I downloaded core.odex and framework.odex from my Samsung Galaxy Player, in order to make some changes for the hidden apis, following this webpage: https://devmaze.wordpress.com/2011/01/18/using-com-android-internal-part-2-hacking-around/
Also, I got baksmali and smali from here: http://forum.xda-developers.com/showthread.php?t=1650243
Now, when I run the command: java -jar baksmali-1.3.3.jar -c :core.odex -x framework.odex, the following error appears:

Failed to install WWW::HtmlUnit in Windows box

I'm trying to install WWW::HTMLUnit on Windows 7. There're step that I run through:
Install Inline::Java 0.53
Install WWW::HTMLUnit 0.15
At step 2, after nmake, I type nmake test to test module but it failed. Here's output:

From above log, I could see that:

I have no idea that I missed anything.
Any help would be appreciated.
Thanks.

I found it.
There's different between path in Unix and Windows system. Unix uses ':' for a delimiter but Windows uses ';'. So what I've done is that open HTMLUnit.pm and change all of ':' to ';'.
With HTMLUnit version 0.15 I made changes at these lines below:
Line 78:
return join ';', map { "$jar_path/$_" } qw( # return join ':', map { "$jar_path/$_" } qw(
Line 127:
$custom_jars = join(';', #{$parameters{'jars'}}); # $custom_jars = join(':', #{$parameters{'jars'}});
Line 148:
CLASSPATH => collect_default_jars() . ";" . $custom_jars, # CLASSPATH => collect_default_jars() . ":" . $custom_jars,
And it works like a magic.

(it wouldn't let me comment on an existing answer)
I see your answer about ':' vs ';'. I'll try to include a fix in the next WWW::HtmlUnit release (I am the author of the perl bindings).
