[jdk17u-dev] RFR: 8048190: NoClassDefFoundError omits original ExceptionInInitializerError

[Goetz Lindenmaier]

I backport this for parity with 17.0.7-oracle.

JCAUtil.java: resolved imports.

X509Factory.java
* resolved imports
* in head, engineGenerateCertificate() is refactored. Part of it 
  is moved to cachedGetX509Cert(), and this is edited.
  I fixed the corresponding, identical code in engineGenerateCertificate() in 
  17. I did not find other places in head where the new method is called.
* The patch removes commitEvent(). This did not apply because of the 'static'
  keyword in head.
