Changed process title on creating symbolic link in the home directory of a user

[henning-gerhardt]

Describe the bug
On calling the used script_createSymLink script the second parameter contains the name of the to be used link. In former times this was the process title but now it is a transformed process.

Some examples:

process title	generated link name
DasNeRu_47771594X-19270110	DasNeRu_47771594X_19270110__[process_id]
denuor._32521638X	denuor__32521638X__[process_id]

I ommitted the real process ids here as they are not part of the issue.

Its look to me that everything in the processtitle which is not a character sign, number or _ get replaced by _. This is may be useful for . character but even for - character? Is there a list which characters got replaced and which not?

Is this a indented behaviour or or can this be adjusted by an other configuration option or just a bug?

Expected behavior
The process title should be taken as a link name or at least should be unmodified used on the script call to it can be changed inside the script if different characters are causing problems

Release
3.6.0

This behaviour is still existing in release 3.7.0.

It seems like we are explicitely replacing everything which is not a a number or a letter by underscore ("_")

Lines 227 to 231 in 0e6e0ee

	if (propertyValue.isEmpty()) {
	return Helper.getNormalizedTitle(process.getTitle()).replaceAll("[^A-Za-z0-9]", "_") + "__[" + process.getId() + "]";
	} else {
	return Helper.getNormalizedTitle(propertyValue.replaceAll("[^A-Za-z0-9]", "_") + "_" + process.getId());
	}

Thank you @BartChris for pointing me in the right direction. Hard coded replacements in depending on a process property value which results different link names. I don't know why this was introduced but this is a good explanation for the current behaviour.
