Steps to reproduce:

1. I created a new Test Case TC999, which looked

import java.util.regex.Pattern

Pattern pattern = Pattern.compile(/^(RiskID(\d+)$/)

2. I wanted to change the source as follows:

(/^(RiskID(\d+)$/)
→
(/^(RiskID|VCAT(\d+)$/)

3. I continued typing on the editor, and saw the editor displayed characters crashed. See the movie above.

I stepped back to v8.1.0 and examined it. — It also has the same problem
I stepped back to v7.9.0 and examined it. — It also has the same problem
I stepped back to v7.8.2 and examined it. — OK.
I stepped back to v7.7.0 and examined it. — OK.
I stepped back to v7.0.8 and examined it. — OK.

This problem occurs since v7.9.0.

According to the Release note, v7.9.0 included

• Upgrade Eclipse IDE from version 4.6 to 4.16.

I believe that this problem occurs since Eclipse v4.16.

When I stepped back to KS v7.8.2, I found the Test Case editor had more of uncomfortable problems. So stepping back does not help me.

I hope Katalon Team to investigate this problem.
