[jira] [Created] (TIKA-1387) Add forbidden-apis checker to TIKA
build
Uwe Schindler created TIKA-1387:
-----------------------------------
Summary: Add forbidden-apis checker to TIKA build
Key: TIKA-1387
URL: https://issues.apache.org/jira/browse/TIKA-1387
Project: Tika
Issue Type: Improvement
Components: general
Reporter: Uwe Schindler
Lucene and many other projects already use the forbidden-apis checker to prevent use of some broken classes/signatures from the JDK. These are especially thing using default character sets or default locales. The forbidden-api checker can also be used to explcitely disallow specific methods, if they have security issues (e.g., creating XML parsers without disabling external entity support).
The attached patch adds the forbidden-api checker to the tika-parent pom file with default configuration.
Running it fails with many errors in TIKA core already:

We should fix those problems.
