NPE from JSyntaxTextArea when loading testplan with 1.9.0

[real....@gmail.com]

Hi folks,

i just upgraded from 1.8.1 to 1.9.0 because i needed the specify resultDir feature (by the way: thanks for that).

But now i can't open my Testplans in GUI mode. I just get an NPE when opening the testplan: (Non GUI mode seems to work though)

The code seems to load a properties file from the classpath in which it expects a specific property (language for some syntax highlighting). I had a look into the ApacheJMeter_core-2.10.jar in lib/ext and it seems like the file is there (org\apache\jmeter\gui\util\textarea.properties). But don't know which key it is looking for.

Not sure if that has anything to do with it, but i recognized that the libs from my jmeter plugins are no longer placed under lib/ext but directly within lib.

Hi,

by looking into the source code it seems that the key called "language" is null in the call to org.apache.jmeter.gui.util.JSyntaxTextArea.setLanguage(JSyntaxTextArea.java:96)

so that seems to be more a Jmeter bug itself than a problem of jmeter-maven-plugin

Seems to be even worse ... for myself ;-)

My own jmeter plugin still had references to Jmeter 2.9 with scope "provided"

Damn me ... Sorry folks.

Michael

But this still wasn't all. So just for the case anybody finds this:

The problem was that the BeanInfo class for my sampler missed the line

p.setValue(TEXT_LANGUAGE, "xml"); // $NON-NLS-1$

after creating a TextArea property like this:

p = property("msgContent", TypeEditor.TextAreaEditor);

You also probably want to have a look at this:

https://github.com/Ronnie76er/jmeter-maven-plugin/wiki/Adding%20Additional%20Libraries%20To%20The%20Classpath

if you want libraries copied into lib/ext you need to specify them in your plugin configuration
