You have been subscribed to a public bug:

A few Java programs have issues with the package fonts-symbola. While projects like Eclipse did not, and Jetbrains, Android Studio, and Netbeans did.
• It does not seem product facing but instead package facing due to trying to run certain code even under a jshell session.
• It does not seem to come directly from a Java version due to multiple versions being affected. 21 and 17 were used.  Although user code may be improved to work around this error, it seems a simple removal of the package fixes the issue as shown below.

Attached are 3 crash logs in text format.  Each of the different
instances fail due to font issues with fonts-symbola.  The exception
Java runs into is:

Caused by: java.lang.NullPointerException: Cannot invoke
"String.startsWith(String)" because "platName" is null

I expect that Java should not have font issues against a addition or removal of a font, and is determined not to be by a specific product but even code running in the jshell_crash.txt file itself which shows the cleanest demonstration of the bug.
The following fixes the error in Java UIs:
• sudo apt purge fonts-symbola.
• sudo rm -rf /var/cache/fontconfig/ && sudo fc-cache -f -v
