[critical] Improve lambda breakpoints when using gradle build server

When using gradle build server, the lambda method name tends to change on large file which I'm not sure of the reason which I have not looked into Java Language Spec on how lambda method names are computed.

What was observed is the method name has the format classMethodName$lambda$#. This cause method name mismatches due to the JDT method name and JDI method name is different.

まず、Gradle build server で lambda breakpoint の不一致を再現し、JDT のメソッド名と JDI のメソッド名を比較します。大きなファイルで lambda メソッド名がどのように計算されるかを調査します。異なる classMethodName$lambda$# 名であっても breakpoint が解決されれば完了です。
