Eric Milles commented on GROOVY-7859: ------------------------------------- I also found that {{String.&toLowerCase}} (for example) is not usable. It results in: {code} assert ['ABC','XYZ'].collect(String.&toLowerCase) == ['abc','xyz'] groovy.lang.MissingMethodException: No signature of method: java.lang.String.toLowerCase() is applicable for argument types: (java.lang.String) values: [ABC] Possible solutions: toLowerCase(), toLowerCase(java.util.Locale), toUpperCase(), toUpperCase(java.util.Locale) at Script1.run(Script1.groovy:1) {code} Should I file a separate bug report for this? > Erroneous method pointer expressions pass STC > --------------------------------------------- > > Key: GROOVY-7859 > URL: https://issues.apache.org/jira/browse/GROOVY-7859 > Project: Groovy > Issue Type: Bug > Components: Static Type Checker > Affects Versions: 2.4.7 > Reporter: Shil Sinha > Assignee: Shil Sinha > > Method pointer expressions are not type checked (with STC enabled).
