Tests fail to run on Leopard, Eclipse 3.4.2, WT 3.8

[jasonsj]

I get the following stack trace when running on Leopard, JVM 1.5, Eclispe 3.4.2, WindowTester 3.8.0. Any ideas? I've ran WindowTester on mac before, but it's been months and I can't remember the configuration.

I added a hack in our base test case class to get around this:

Code: Select all

if (Platform.getOS().contains(Platform.OS_MACOSX))
    System.setProperty("java.awt.headless", Boolean.FALSE.toString()); //$NON-NLS-1$

Setting it as a VM argument didn't seem to work.

I swear this worked before. I've stayed up to date on Apple's Java updates. I verified my Java Preferences to use J2SE 5.0 by default.

[Phil Quitslund]

This is curious. Using WT 3.9 on Leopard, 3.4.2 and the default 1.5.0 JVM I'm not seeing this. At some point you might try updating to 3.9 and see if the need for the work-around persists.

Thanks!

[jasonsj]

I forgot to mention, I initially had upgraded to 3.9.0 and got the same error. I thought downgrading would fix it, but it didn't.

[Phil Quitslund]

Cool. Thanks for adding that bit. It is curious and I'll poke around. In the meantime, I'm happy you have a work-around and this post might provide another:

Keep us posted if you make any progress and we'll do the same on our end.

Thanks!
