Solr 5.1 ignores SOLR_JAVA_MEM setting

[Ere Maijala]

Folks, just a quick heads-up that apparently Solr 5.1 introduced a 
change in bin/solr that overrides SOLR_JAVA_MEM setting from solr.in.sh 
or environment. I just filed 
https://issues.apache.org/jira/browse/SOLR-7392. The problem can be 
circumvented by using SOLR_HEAP setting, e.g. SOLR_HEAP="32G", but it's 
not mentioned in solr.in.sh by default.
