The regular expression in GccMemoryMapParser.java Line 92 does not match railing whitespaces.

Suggestion for a solution: {{SECTIONS\\s*?\\r?\\n?

}}

if your Linker command file looks like this:
{{SECTION
{}}
the regex will not match.

If it doesn't match, it fails with this stack trace (which is bad either):
