Describe the bug

[martinlippert]

Looks like something is seriously going wrong here. Can you take a look at the Error Log View to see if there is a related error being logged that includes a stack trace and if so, post that here?

In addition to that it would be great if you could enable the logging for the Spring Boot Language Server via Preferences -> Language Servers -> Spring Language Servers and enable the Spring Boot checkbox there. After a restart, this will cause a console tab to be opened as soon as the language server starts up behind the scenes and logs all the output from that process to that console tab. Would be great if you could attach that output here as well.

Also, if you have a sample project that helps to reproduce the problem and a few steps how to reproduce this, that would be awesome and help a lot as well.

[martinlippert]

Thanks @huanglppp for the details from the Error Log View. Could you also take a look at this:

In addition to that it would be great if you could enable the logging for the Spring Boot Language Server via Preferences -> Language Servers -> Spring Language Servers and enable the Spring Boot checkbox there. After a restart, this will cause a console tab to be opened as soon as the language server starts up behind the scenes and logs all the output from that process to that console tab. Would be great if you could attach that output here as well.

That would be great. Also a sample project would be great and a few steps how to reproduce this problem. Thanks!!!

[martinlippert]

Thanks @guerricm for attaching the error log, the exception in there is interesting. Do you have a sample project that you could attach that reproduces the issue (from a fresh STS 4.12.1 installation and an empty workspace)? That would be awesome.

Thanks @guerricm for the error log, this part of the exception pointed me into the right direction:

java.lang.NullPointerException: Cannot invoke "java.lang.Integer.intValue()" because the return value of "java.util.LinkedHashMap.get(Object)" is null
at org.springframework.ide.vscode.commons.jdtls.Wrappers$2.dimensions(Wrappers.java:108)

at org.springframework.ide.vscode.boot.metadata.types.TypeUtil.lambda$getProperties$5(TypeUtil.java:774)

Should be fixed now. Ships as part of STS 4.13.0 mid of December.
