This is a defect. The 'bad' method names are enumerated, and deleteChars was missing from the list. Fixed in jet-main#054c426c86d3 Integrated into 'main-silver', will be available in build *201703160002* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress) Changeset: http://hg.netbeans.org/main-silver/rev/054c426c86d3 User: Svata Dedic <sdedic@netbeans.org> Log: #269774: added missing SBuilder mutating method |
PROBLEM The "Replace StringBuffer/Builder by String" hint breaks some code, when a StringBuilder-specific method is used. PROBLEM EXAMPLE This snippet of code produces a hint to replace the StringBuilder with a String: String str = "Hello World!"; StringBuilder sb = new StringBuilder(str); sb.deleteCharAt(5); When the suggested replacement is applied, the snippet is changed to this: String str = "Hello World!"; String sb = str; sb.deleteCharAt(5); But then a compile error arises, because, of course, sb.deleteCharAt() doesn't exist. SUGGESTED CHANGE The hint should be suppressed when a StringBuilder-specific method is used. FURTHER INFORMATION This bug looks like bug #239082. Here are my system details, however, I don't think they have something to do with the bug.
