Uwe Schindler commented on SOLR-11795:
--------------------------------------
About snakeyaml: The Exception handling is broken in multiple ways:
https://bitbucket.org/asomov/snakeyaml/src/9ffe9d8b2ba4e5eabde045d407799a71997cda20/src/main/java/org/yaml/snakeyaml/introspector/PropertyUtils.java?at=default&fileviewer=file-view-default#PropertyUtils.java-124:151
- Uses e.printStackTrace() -> forbidden, this is not acceptable behaviour of a
library
- catches only those exceptions, that eclipse autogenerated (of course... this
is incredible shitty code, sorry!), of curse missing the runtime exceptions
thrown by Java 9 when illegal access is denied
- does not use AccessController.doPrivileged, so it can never be made safe with
security manager!
IMHO, the only workaround here (without patching this library) is to install a
security amnager that explicitely denies deep refelection access to java.beans
(so at least the secruity exception is catched).
Or much simpler: Get rid of YAML!
