toString() Object View should catch exceptions, or default to false

When using the vscode java debugger, the experience can be really bad because some variables cannot be inspected seemingly for no reason. This gives the impression that the extension is still very buggy. It took me a long time to find out that disabling the toString() Object View solves that problem.

Likely there are exceptions thrown during toString() execution for those variables. These should either be caught, or the default for "Enable toString() Object View" should be false.

Environment

• Operating System: MacOS Ventura 13.2
• JDK version: debugee is OpenJDK Runtime Environment Homebrew (build 11.0.18+0)
• Visual Studio Code version: 1.75.1 (Universal) Commit: 441438abd1ac652551dbe4d408dfcec8a499b8bf
• Java extension version: v1.14.0
• Java Debugger extension version: 0.48.0 - 2023-02-01

Steps To Reproduce

1. set a breakpoint and look at Variables View, where some variables cannot be inspected
   
2. set "Enable toString() Object View" to false
   
3. Now the variables can be expanded:
   

Current Result

Some variables cannot be inspected

Expected Result

It should be possible to inspect all variables, regardless of whether their toString() method throws an exception

该 issue 没有指明源文件、测试或入口点；请在启用 Enable toString() Object View 的情况下，在 Variables View 中复现该问题，然后跟踪调试器的 toString() 求值路径。完成标准是：即使变量的 toString() 抛出异常，每个变量仍可展开和检查，并且该行为由适当的回归测试覆盖。
