Re: [platform-swt-dev] SWT 4.8 and CentOS 6.10

There was a related
change in 4.8:

Bug
521487: [JNI] Expose cached
JVM pointer 

Maybe that introduced
the bug?

That's really weird. The function in
question is just:
JNIEXPORT void JNICALL OS_NATIVE(_1cachejvmptr)
    (JNIEnv *env, jclass that)
{
    /* cache the JavaVM pointer */
    if (cached_jvm == NULL) (*env)->GetJavaVM(env, &cached_jvm);
}

Which java version is that ?

Hi,

When launching SmartGit 18.2 which uses SWT 4.8 on a CentOS 6.10 64-bit, I'm getting following exception:

SmartGit 18.1 uses SWT 4.7 and this works fine.

Is CentOS 6 not supported any more by SWT 4.8?

As CentOS 6 is GTK 2.x based it's in
a "if it works" state. And ability to even start on systems that
don't have GTK 3 will be dropped in 4.10 release (Dec) - announced yesterday
on cross-project mailing list and at https://wiki.eclipse.org/Eclipse/PMC.

Is there a list of officially supported Linux versions?

Due to the crazy amount of different
distributions and etc. there is a a list of "target environments"
- aka environments that someone stated an intent to test and work on bugs
for. It's available at https://www.eclipse.org/eclipse/development/plans/eclipse_project_plan_4_8.xml#target_environments. This is by no means an exclusive list and IMHO any not too old (aka has
GTK 3) Linux distribution that doesn't deviate too much from upstream projects
should be working fine.

Thanks in advance.
