Release Note: Unify Syntax of `CompileOnly` and `CompileCommand` - Resolved
Description
At the moment CompileCommand and CompileOnly use different syntax for wildcarding.
In some cases it is impossible to just take pattern used with CompileOnly and plug it into compile command file. Syntax used by CompileOnly is also not very intuitive.

It would be nice if both commands will use the same syntax for wildcarding.

Still valid. Fix this when touching this code the next time.

-XX:CompileOnly is used in about 110 tests. Many of them rely on multiple patterns, and most reply on implicit wildcard matching. Alternatives: 1) Fix same wildcarding as rest of compile command and change patterns in all the tests 2) Remove CompileOnly and change to CompileCommand in all the tests including wildcarding (We could consider multipatterns too - CompileCommand=compileonly,java.*,com/sun.*,...) 3) Close as WNF and fix the documentation (JDK-8071652)

Sounds good.

I think the consensus is to remove the standalone CompileOnly flag. I will not do this as part of the compiler control JEP. Will follow up with this after Compiler Control is integrated.

CompileOnly is used in 104 files in the JDK. Investigate making it an alias for -XXCompileCommnad=compileonly instead

There already are a commandline CompileCommand for compileonly. "-XX:CompileCommand=compileonly,java.lang.String::length". We could just retire the standalone version.

It is good suggestion. We will do it when we have time.

Note that CompileOnly may accept incorrect patterns like "java::lang::String::length" and treat it as a method "length" defined in any class that has substring "java" it fully qualified name. The same in case of "java.lang.String.length". Since it does not print any warnings/errors or messages that describe what pattern will be used (as in case of CompileCommand), it could lead to unwanted behaviour of compiler. If you think that this RFE should be closed, then please file a new bug to address this particular issue.
