Hi,

Whenever I use Junit @Test annotation in Kotlin code(see [1] below), Eclipse (or perhaps Kotlin plug-in for Eclipse) generates a bunch of errors that pop up every ten seconds or so, very annoying:

```
An internal error occurred during: "Kotlin Analysis".
Wrong annotation argument: 0

An internal error occurred during: "Install semantic highlighting".
Wrong annotation argument: 0

An internal error occurred during: "Compute launch button tooltip".
Wrong annotation argument: 0

An internal error occurred during: "Update occurrence annotations".
Wrong annotation argument: 0

```

The code[1] builds and runs without errors, the test is run as well and the test report is generated successfully.

Any ideas? Anything I can do to prevent/suspend the above errors? Thanks

My environment:

- Openjdk 11.0.2 2018-10-16
- Eclipse Java EE IDE for Web Developers, Version: 2018-09 (4.9.0) Build id: 20180917-1800
- Kotlin plug-in: 0.8.12
- Junit 4.12

[1] - test code where the above errors were generated

```
package test

import org.junit.Assert.assertTrue
import org.junit.Test

class KotlinTests {
	companion object a {
		@JvmStatic
		fun main(args : Array<String>) {
			println("In KotlinTests main: argsSize=${args.size}.")
			println("In KotlinTests main: args=${args.toString()}.")
			println("In KotlinTests main: args0=${args[0]}, args1=${args[1]}.")
		}		
	}
	@Test
	fun runASimpleTest() {
		println("In runASimpleTest")
		assertTrue(true)
    }
}

```

Am getting 404 error on that link.

```
# 404

## Invalid download path: repository/download/Kotlin_EclipsePlugin/latest.lastSuccessful

```

Tried several links on [Ring](https://teamcity.jetbrains.com/repository/download/Kotlin_EclipsePlugin/) page, all of them generate “404 Invalid download path” error for me. Thanks

It look like you are trying to use this addresses via web browser. The plugins from update sites are intended to be installed via eclipse `Help -> Install new software` dialog.
