java: Parameter keys are not escaped properly

[lorenzleutgeb]

Description

Note the | character in the parameter key. This translates to:

  public static final String SERIALIZED_NAME_UPDATED_AT|GT = "updated_at|gt";
  @SerializedName(SERIALIZED_NAME_UPDATED_AT|GT)
  private OffsetDateTime updatedAt|gt = null;

... which does not parse as Java.
