Eclipse does not start after Java 11 is installed

Introduction

I installed Java 11 at work and Eclipse didn't start. At first, I struggled without knowing the cause at all, so I decided to write an article as a record.

Status

Initial state

Since it was old Java as shown below, I decided to upgrade the Java version in my spare time. Eclipse uses the Japanese version of Pleiades.

• OS：Windows 10 Pro
• Java：Oracle Java 8
• Eclipse：Eclipse 4.6（Neon）

State after Java version upgrade

I installed "Amazon Corretto" which is free to use and easy to install.

• OS：Windows 10 Pro
• Java：Amazon Corretto 11
• Eclipse：Eclipse 4.6（Neon）

Problems that occurred

After the Eclipse splash screen was displayed, the dialog ʻAn error has occurred. See the log file ...` appeared and Eclipse did not start.

counter-measure

• When I installed the latest version of Eclipse by referring to the following article, Eclipse started successfully.
• Eclipse-Oxygen does not start on Java 11 or above
• By the way, the version of Eclipse installed this time is the latest version of "Release 2019-09".

Summary

• When I upgraded from Java 7 to Java 8, I don't think there was a symptom that Eclipse did not start, so I was quite surprised this time.
• At first, I thought that there was a problem with Amazon Corretto ... but after investigating various things, I found that the same symptom appeared in Java 10 or later, and finally I could solve it with a relatively simple method. It was good.
• There were some small programs that I didn't include in version control, but it helped me because I could easily import the code from my existing workspace.
