SpringToolSuite (x_86_64 option) IDE keeps crashing frequently.

Describe the bug
The STS IDE keeps crashing whenever I try to use the AutoComplete/Suggestion window while writing in the Java class. For e.g. ResponseEntity -> type period symbol -> it hangs up after that event. Next, a pop-up window opens which asks me to either Wait or Force Quit the IDE. The Wait option just continues a few times after which it crashes and quits on it's own.

I am not able to use this IDE due to this issue. Please provide a solution how to fix this problem. Thank you!

To Reproduce
Download the latest STS IDE or even try Spring STS 4.2.2 Release version ( Linux - x86-64) . Then, follow the steps mentioned in the previous paragraph.

Sample
A copy of the PID log file( with stacktrace and thread dump which was automatically generated) is attached for your reference. PLease note that it is happening frequently. Changing the memory XmX and Xms to higher values does not make any difference.

It'd be interesting to see the Boot Language server log file. Please enable Spring Boot Language Server logging via:

Reproduce the hang and attach the log file here.

As a possible workaround: go in the preferences and uncheck the checkboxes below. This will disable Spring Boot Language Server and consequently contributions made by STS into the Java completion proposals.

The JVM crash report that you attached seems to point into the direction of a crashing webkit library, so maybe a duplicate of eclipse-platform/eclipse.platform.swt#1108 ?

There is also a workaround mentioned ("Start with GDK_BACKEND=x11"), would be good to know whether that helps or not.

Closing this one here as a duplicate of #1230. There is also some information on where to get snapshot builds from which already include a fix.
