I also saw a small improvement in application startup time.

Tyler Benson 35e00686b3 Imply not(isInterface()) call for expensive matchers
Also remove from simple named("some.name") matchers to avoid metadata lookup.

Tyler Benson f70c35842d Move matchers to separate package and split matcher classes out 2020-02-24 08:31:12 -08:00
Laplie Anderson d45ead1284 split matching into safeExtendsClass and safeHasInterface 2020-02-19 21:22:17 -05:00
Tyler Benson 51bffa2e8a Move agent api classes to bootstrap package so they're not analyzed by muzzle
Also move jdbc classes to bootstrap to reduce size and complexity of those reference checkers.

These changes reduce the total file size of these instrumentation classes by 635k, which should also result in decent memory savings.

dougqh 6b096c2240 Replacing Advice.class references
Replacing Advice.class references with string construction.

This stops the JVM from loading the Advice classes which are used as templates for byte buddy and doesn't ever need to be run directly.

This eliminates ~130 class loads at start-up -- and saves 0.5MiB in metaspace

Tyler Benson a8ca47ed03 Skip spring controller and dropwizard trace if no trace present
Also prefer early return instead of deep nesting for null check.

Tyler Benson 7db4602253 Fix jax-rs-client minimum supported version
Can’t be completely sure since many of these versions don’t show up in a maven range query used by muzzle.
