I was browsing the STS4 changelog when I noticed you guys fixed #704 by copying jdt.ls' ParentProcessWatcher.java. Surely an honest mistake but you can't change the original copyright owner from https://github.com/eclipse/eclipse.jdt.ls/blob/64b15c5a9e5b11f62ceb5163ceb6930d5dea7129/org.eclipse.jdt.ls.core/src/org/eclipse/jdt/ls/core/internal/ParentProcessWatcher.java

https://github.com/spring-projects/sts4/blob/22eb13cc9fa4a3d92e4381ab6a69216404f0aa9b/headless-services/commons/commons-language-server/src/main/java/org/springframework/ide/vscode/commons/languageserver/util/ParentProcessWatcher.java#L1-L10

Original license is EPLv2. It might be OK to downgrade, but I dunno, IANAL
