Eclipse "Unable to instantiate class JavaSourceLookupDirector, Expecting stackmap frame at branch target 53" after upgrade

Question

Just updated eclipse and now I can't run my spring application anymore.

Version: Eclipse IDE for Java Developers (includes Incubating components) Version: 2020-12 (4.18.0) Build id: 20201210-1552

Error message:

Plug-in "org.eclipse.jdt.launching" was unable to instantiate class "org.eclipse.jdt.internal.launching.JavaSourceLookupDirector". Expecting a stackmap frame at branch target 53 Exception Details: Location: org/eclipse/debug/core/sourcelookup/AbstractSourceLookupDirector.dispose()V @29: goto Reason: Expected stackmap frame at this location.

Installed Jdk is: AdoptopenJDK 11.0.9.101-hotspot (also selected as default under Installed JRE)

I already had problems starting eclipse after the update so I set in eclipse.ini:

-vm C:\Program Files\AdoptOpenJDK\jdk-11.0.9.101-hotspot\bin

The application is a normal java spring application, with "gradlew bootRun" runs perfectly fine.

Honestly how can such an obscure error occur? Can anyone help with this issue?

Answer 1

I faced similar issue with eclipse version Version: 2020-12 (4.18.0) where I was getting below error

Plug-in "org.eclipse.jdt.launching" was unable to instantiate class org.eclipse.jdt.internal.launching.JavaSourceLookupDirector".Expecting a stackmap frame at branch target 53

I was running spring boot app with java but found kotlin was also installed which was not required for my project.

To fix, I uninstalled kotlin development tools and restarted eclipse which worked pretty well

You can view all installed software with Help > About Eclipse IDE > Installation details. It might be helpful when you only keep required softwares while uninstalling all non required ones.

Answer 2

Uninstalling Kotlin from About Eclipse IDE> Installation Details > Kotlin > Uninstall solved my problem.

Answer 3

I had exactly the same issue, but I need to import and start Kotlin project, so uninstalling Kotlin plugin is not an option.

My setup: Eclipse 2021-03 + Kotlin Plugin 0.8.21.

Installing latest AspectJ Development Tools (today it is 2.2.4) worked for me, give it a try.
