How to reproduce?
Start an embedded Jetty from an application that uses classpath wildcards.

As far as I'm aware, that's not a valid classpath with globs.

"D:\testlibs*" // this isn't supported.
"D:\testlibs\*" // this should be supported.

Java places some restrictions on how you use wildcard / globs.

• It can only be at the end of a String.
• It must be after a directory slash.
• Only a "*" is supported (meaning all files in the current directory)

I have updated the description, it was with a backslash at the end but the markdown syntax swallowed it. It is a valid classpath configuration, the applications starts with it.

Now I see that the issue is older : #11092 .

[joakime]

I think I see where we can make an improvement in #11092

[joakime]

I have a possibly fix in #12287 can you test it?

[cliviu]

I have a possibly fix in #12287 can you test it?

When will be the next version available?

[joakime]

When will be the next version available?

Jetty 12 release cadence is to stage the next release at the last thursday of every month, then once testing of the stage is complete release it. Sometimes it goes quick, sometimes it takes longer when the stage testing fails (we have to restage after fixing what we discover, etc)

When it is staged, would be a good time to test.
